The game's main character is Annalyn, a brave girl with a fierce and loyal pet dog. Unfortunately, disaster strikes, as her best friend was kidnapped while searching for berries in the forest. Annalyn will try to find and free her best friend, optionally taking her dog with her on this quest. + +After some time spent following her best friend's trail, she finds the camp in which her best friend is imprisoned. It turns out there are two kidnappers: a mighty knight and a cunning archer. + +Having found the kidnappers, Annalyn considers which of the following actions she can engage in: + +- Fast attack: a fast attack can be made if the knight is sleeping, as it takes time for him to get his armor on, so he will be vulnerable. +- Spy: the group can be spied upon if at least one of them is awake.

Check if a fast attack can be made + +Implement the (_static_) `AnnalynsInfiltration.canFastAttack()` method that takes a boolean value that indicates if the knight is awake.

An **array** is a collection that has a fixed size/length and whose elements must all be of the same type. Elements can be assigned to an array or retrieved from it using an index. Java arrays are zero-based, meaning that the first element's index is always zero: + +```java +// Declare array with explicit size (size is 2) +int[] twoInts = new int[2]; + +// Assign second element by index +twoInts[1] = 8; + +// Retrieve the second element by index and assign to the int element +int element = twoInts[1]; +``` + +Arrays can also be defined using a shortcut notation that allows you to both create the array and set its value. As the compiler can now tell how many elements the array will have, the length can be omitted: + +```java +// Two equivalent ways to declare and initialize an array (size is 3) +int[] threeIntsV1 = new int[] { 4, 9, 7 }; +int[] threeIntsV2 = { 4, 9, 7 }; +``` + +Arrays can be manipulated by either calling an array instance's methods or properties, or by using the static methods defined in the `Arrays` class. + +The fact that an array is also a _collection_ means that, besides accessing values by index, you can iterate over _all_ its values using a `foreach` loop: + +```java +char[] vowels = { 'a', 'e', 'i', 'o', 'u' }; + +for(char vowel:vowels) { + // Output the vowel + System.out.print(vowel); +} + +// => aeiou +``` + +If you want more control over which values to iterate over, a `for` loop can be used: + +```java +char[] vowels = { 'a', 'e', 'i', 'o', 'u' }; + +for (int i = 0; i < 3; i++) { + // Output the vowel + System.out.print(vowels[i]); +} + +// => aei +``` + +## Instructions + +You're an avid bird watcher that keeps track of how many birds have visited your garden in the last seven days. + +You have six tasks, all dealing with the numbers of birds that visited your garden. + +## 1.

Examples are `-6`, `0`, `1`, `25`, `976` and `-500000`. +- Floating-point numbers: numbers with zero or more digits behind the decimal separator. Examples are `-20.4`, `0.1`, `2.72`, `16.984025` and `1024.0`. + +The two most common numeric types in Java are `int` and `double`. An `int` is a 32-bit integer and a `double` is a 64-bit floating-point number. + +Arithmetic is done using the standard arithmetic operators. Numbers can be compared using the standard numeric comparison operators and the equality (`==`) and inequality (`!=`) operators. + +Java has two types of numeric conversions: + +1. Implicit conversions: no data will be lost and no additional syntax is required. +2. Explicit conversions: data could be lost and additional syntax in the form of a _cast_ is required. + +As an `int` has less precision than a `double`, converting from an `int` to a `double` is safe and is thus an implicit conversion. However, converting from a `double` to an `int` could mean losing data, so that requires an explicit conversion. + +In this exercise you must conditionally execute logic. The most common way to do this in Java is by using an `if/else` statement: + +```java +int x = 6; + +if (x == 5) { + // Execute logic if x equals 5 +} else if (x > 7) { + // Execute logic if x greater than 7 +} else { + // Execute logic in all other cases +} +``` + +The condition of an `if` statement must be of type `boolean`. Java has no concept of _truthy_ values. + +## Instructions + +In this exercise you'll be writing code to analyze the production of an assembly line in a car factory. The assembly line's speed can range from `0` (off) to `10` (maximum). + +At its lowest speed (`1`), `221` cars are produced each hour. The production increases linearly with the speed. So with the speed set to `4`, it should produce `4 * 221 = 884` cars per hour. However, higher speeds increase the likelihood that faulty cars are produced, which then have to be discarded. The following table shows how speed influences the success rate: + +- `1` to `4`: 100% success rate. +- `5` to `8`: 90% success rate. +- `9`: 80% success rate. +- `10`: 77% success rate. + +You have two tasks. + +## 1.

The fields and methods of a class are known as its _members_. + +Access to members can be controlled through access modifiers, the two most common ones being: + +- `public`: the member can be accessed by any code (no restrictions). +- `private`: the member can only be accessed by code in the same class. + +You can think of a class as a template for creating instances of that class. To create an instance of a class (also known as an _object_), the `new` keyword is used: + +```java +class Car { +} + +// Create two car instances +Car myCar = new Car(); +Car yourCar = new Car(); +``` + +Fields have a type and a name (defined in camelCase) and can be defined anywhere in a class (by convention cased in PascalCase): + +```java +class Car { + // Accessible by anyone + public int weight; + + // Only accessible by code in this class + private String color; +} +``` + +One can optionally assign an initial value to a field. If a field does _not_ specify an initial value, it wll be set to its type's default value. An instance's field values can be accessed and updated using dot-notation. + +```java +class Car { + // Will be set to specified value + public int weight = 2500; + + // Will be set to default value (0) + public int year; +} + +Car newCar = new Car(); +newCar.weight; // => 2500 +newCar.year; // => 0 + +// Update value of the field +newCar.year = 2018; +``` + +Private fields are usually updated as a side effect of calling a method. Such methods usually don't return any value, in which case the return type should be `void`: + +```java +class CarImporter { + private int carsImported; + + public void ImportCars(int numberOfCars) + { + // Update private field from public method + carsImported = carsImported + numberOfCars; + } +} +``` + +## Instructions + +In this exercise you'll be playing around with a remote controlled car, which you've finally saved enough money for to buy. + +Cars start with full (100%) batteries. Each time you drive the car using the remote control, it covers 20 meters and drains one percent of the battery. + +The remote controlled car has a fancy LED display that shows two bits of information: + +- The total distance it has driven, displayed as: `"Driven meters"`. +- The remaining battery charge, displayed as: `"Battery at %"`. + +If the battery is at 0%, you can't drive the car anymore and the battery display will show `"Battery empty"`. + +You have six tasks, each of which will work with remote controlled car instances. + +## 1. Buy a brand-new remote controlled car + +Implement the (_static_) `ElonsToyCar.buy()` method to return a brand-new remote controlled car instance: + +```java +ElonsToyCar car = ElonsToyCar.buy(); +``` + +## 2. Display the distance driven + +Implement the `ElonsToyCar.distanceDisplay()` method to return the distance as displayed on the LED display: + +```java +ElonsToyCar car = ElonsToyCar.buy(); +car.distanceDisplay(); +// => "Driven 0 meters" +``` + +## 3. Display the battery percentage + +Implement the `ElonsToyCar.batteryDisplay()` method to return the battery percentage as displayed on the LED display: + +```java +ElonsToyCar car = ElonsToyCar.buy(); +car.batteryDisplay(); +// => "Battery at 100%" +``` + +## 4. Update the number of meters driven when driving + +Implement the `ElonsToyCar.drive()` method that updates the number of meters driven: + +```java +ElonsToyCar car = ElonsToyCar.buy(); +car.drive(); +car.drive(); +car.distanceDisplay(); +// => "Driven 40 meters" +``` + +## 5. Update the battery percentage when driving + +Update the `ElonsToyCar.drive()` method to update the battery percentage: + +```java +ElonsToyCar car = ElonsToyCar.buy(); +car.drive(); +car.drive(); +car.batteryDisplay(); +// => "Battery at 98%" +``` + +## 6. Prevent driving when the battery is drained + +Update the `ElonsToyCar.drive()` method to not increase the distance driven nor decrease the battery percentage when the battery is drained (at 0%): + +```java +ElonsToyCar car = ElonsToyCar.buy(); + +// Drain the battery +// ... + +car.distanceDisplay(); +// => "Driven 2000 meters" + +car.batteryDisplay(); +// => "Battery empty" +``` + +## Source + +### Created by + +- @mikedamay + +### Contributed to by + +- @mirkoperillo \ No newline at end of file diff --git a/elons-toy-car/build.gradle b/elons-toy-car/build.gradle new file mode 100644 index 0000000..8bd005d --- /dev/null +++ b/elons-toy-car/build.gradle @@ -0,0 +1,24 @@ +apply plugin: "java" +apply plugin: "eclipse" +apply plugin: "idea" + +// set default encoding to UTF-8 +compileJava.options.encoding = "UTF-8" +compileTestJava.options.encoding = "UTF-8" + +repositories { + mavenCentral() +} + +dependencies { + testImplementation "junit:junit:4.13" + testImplementation "org.assertj:assertj-core:3.15.0" +} + +test { + testLogging { + exceptionFormat = 'full' + showStandardStreams = true + events = ["passed", "failed", "skipped"] + } +} diff --git a/elons-toy-car/build/classes/java/main/ElonsToyCar.class b/elons-toy-car/build/classes/java/main/ElonsToyCar.class new file mode 100644 index 0000000..7b5dcb6 Binary files /dev/null and b/elons-toy-car/build/classes/java/main/ElonsToyCar.class differ diff --git a/elons-toy-car/build/classes/java/test/ElonsToyCarTest.class b/elons-toy-car/build/classes/java/test/ElonsToyCarTest.class new file mode 100644 index 0000000..a5256cd Binary files /dev/null and b/elons-toy-car/build/classes/java/test/ElonsToyCarTest.class differ diff --git a/elons-toy-car/build/reports/tests/test/classes/ElonsToyCarTest.html b/elons-toy-car/build/reports/tests/test/classes/ElonsToyCarTest.html new file mode 100644 index 0000000..43c98b8 --- /dev/null +++ b/elons-toy-car/build/reports/tests/test/classes/ElonsToyCarTest.html @@ -0,0 +1,141 @@ + + + + + +Test results - Class ElonsToyCarTest + + + + + +

Assigning a value to a name is referred to as defining a variable. A variable is defined by explicitly specifying its type. + +```java +int explicitVar = 10; +``` + +Updating a variable's value is done through the `=` operator. Once defined, a variable's type can never change. + +```java +int count = 1; // Assign initial value +count = 2; // Update to new value + +// Compiler error when assigning different type +// count = false; +``` + +Java is an [object-oriented language][object-oriented-programming] and requires all functions to be defined in a _class_. The `class` keyword is used to define a class. + +```java +class Calculator { + // ... +} +``` + +A function within a class is referred to as a _method_. Each method can have zero or more parameters. All parameters must be explicitly typed, there is no type inference for parameters. Similarly, the return type must also be made explicit. Values are returned from functions using the `return` keyword. To allow a method to be called by other classes, the `public` access modifier must be added. + +```java +class Calculator { + public int add(int x, int y) { + return x + y; + } +} +``` + +Invoking a method is done by specifying its class and method name and passing arguments for each of the method's parameters. + +```java +int sum = new Calculator().add(1, 2); +``` + +Scope in Java is defined between the `{` and `}` characters. + +Java supports two types of comments. Single line comments are preceded by `//` and multiline comments are inserted between `/*` and `*/`. + +[object-oriented-programming]: https://docs.oracle.com/javase/tutorial/java/javaOO/index.html + +## Instructions + +In this exercise you're going to write some code to help you cook a brilliant lasagna from your favorite cooking book. + +You have four tasks, all related to the time spent cooking the lasagna. + +## 1.

Calculate the remaining oven time in minutes + +Define the `remainingMinutesInOven()` method that takes the actual minutes the lasagna has been in the oven as a parameter and returns how many minutes the lasagna still has to remain in the oven, based on the expected oven time in minutes from the previous task. + +```java +Lasagna lasagna = new Lasagna(); +lasagna.remainingMinutesInOven(30); +// => 10 +``` + +## 3. Calculate the preparation time in minutes + +Define the `preparationTimeInMinutes()` method that takes the number of layers you added to the lasagna as a parameter and returns how many minutes you spent preparing the lasagna, assuming each layer takes you 2 minutes to prepare. + +```java +Lasagna lasagna = new Lasagna(); +lasagna.preparationTimeInMinutes(2); +// => 4 +``` + +## 4. Calculate the total working time in minutes + +Define the `totalTimeInMinutes()` method that takes two parameters: the first parameter is the number of layers you added to the lasagna, and the second parameter is the number of minutes the lasagna has been in the oven. The function should return how many minutes in total you've worked on cooking the lasagna, which is the sum of the preparation time in minutes, and the time in minutes the lasagna has spent in the oven at the moment. + +```java +Lasagna lasagna = new Lasagna(); +lasagna.totalTimeInMinutes(3, 20); +// => 26 +``` + +## Source + +### Created by + +- @mirkoperillo \ No newline at end of file diff --git a/lasagna/build.gradle b/lasagna/build.gradle new file mode 100644 index 0000000..8bd005d --- /dev/null +++ b/lasagna/build.gradle @@ -0,0 +1,24 @@ +apply plugin: "java" +apply plugin: "eclipse" +apply plugin: "idea" + +// set default encoding to UTF-8 +compileJava.options.encoding = "UTF-8" +compileTestJava.options.encoding = "UTF-8" + +repositories { + mavenCentral() +} + +dependencies { + testImplementation "junit:junit:4.13" + testImplementation "org.assertj:assertj-core:3.15.0" +} + +test { + testLogging { + exceptionFormat = 'full' + showStandardStreams = true + events = ["passed", "failed", "skipped"] + } +} diff --git a/lasagna/gradle/wrapper/gradle-wrapper.jar b/lasagna/gradle/wrapper/gradle-wrapper.jar new file mode 100644 index 0000000..249e583 Binary files /dev/null and b/lasagna/gradle/wrapper/gradle-wrapper.jar differ diff --git a/lasagna/gradle/wrapper/gradle-wrapper.properties b/lasagna/gradle/wrapper/gradle-wrapper.properties new file mode 100644 index 0000000..ae04661 --- /dev/null +++ b/lasagna/gradle/wrapper/gradle-wrapper.properties @@ -0,0 +1,5 @@ +distributionBase=GRADLE_USER_HOME +distributionPath=wrapper/dists +distributionUrl=https\://services.gradle.org/distributions/gradle-7.5.1-bin.zip +zipStoreBase=GRADLE_USER_HOME +zipStorePath=wrapper/dists diff --git a/lasagna/gradlew b/lasagna/gradlew new file mode 100755 index 0000000..a69d9cb --- /dev/null +++ b/lasagna/gradlew @@ -0,0 +1,240 @@ +#!/bin/sh + +# +# Copyright © 2015-2021 the original authors. +# +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# +# https://www.apache.org/licenses/LICENSE-2.0 +# +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. +# + +############################################################################## +# +# Gradle start up script for POSIX generated by Gradle. +# +# Important for running: +# +# (1) You need a POSIX-compliant shell to run this script.

A constructor is a special type of method whose goal is to initialize a newly created instance. Constructors look like regular methods, but without a return type and with a name that matches the classes' name. + +```java +class Library { + private int books; + + public Library() { + // Initialize the books field + this.books = 10; + } +} + +// This will call the constructor +var library = new Library(); +``` + +Like regular methods, constructors can have parameters. Constructor parameters are usually stored as (private) fields to be accessed later, or else used in some one-off calculation. Arguments can be passed to constructors just like passing arguments to regular methods. + +```java +class Building { + private int numberOfStories; + private int totalHeight; + + public Building(int numberOfStories, double storyHeight) { + this.numberOfStories = numberOfStories; + this.totalHeight = numberOfStories * storyHeight; + } +} + +// Call a constructor with two arguments +var largeBuilding = new Building(55, 6.2); +``` + +## Instructions + +In this exercise you'll be organizing races between various types of remote controlled cars. Each car has its own speed and battery drain characteristics. + +Cars start with full (100%) batteries. Each time you drive the car using the remote control, it covers the car's speed in meters and decreases the remaining battery percentage by its battery drain. + +If a car's battery is below its battery drain percentage, you can't drive the car anymore. + +Each race track has its own distance. Cars are tested by checking if they can finish the track without running out of battery. + +You have six tasks, each of which will work with remote controller car instances. + +## 1. Creating a remote controlled car + +Allow creating a remote controller car by defining a constructor for the `NeedForSpeed` class that takes the speed of the car in meters and the battery drain percentage as its two parameters (both of type `int`): + +```java +int speed = 5; +int batteryDrain = 2; +var car = new NeedForSpeed(speed, batteryDrain); +``` + +## 2. Creating a race track + +Allow creating a race track by defining a constructor for the `RaceTrack` class that takes the track's distance in meters as its sole parameter (which is of type `int`): + +```java +int distance = 800; +var raceTrack = new RaceTrack(distance); +``` + +## 3. Drive the car + +Implement the `NeedForSpeed.drive()` method that updates the number of meters driven based on the car's speed. Also implement the `NeedForSpeed.distanceDriven()` method to return the number of meters driven by the car: + +```java +int speed = 5; +int batteryDrain = 2; +var car = new NeedForSpeed(speed, batteryDrain); +car.drive(); + +car.distanceDriven(); +// => 5 +``` + +## 4. Check for a drained battery + +Update the `NeedForSpeed.drive()` method to drain the battery based on the car's battery drain. Also implement the `NeedForSpeed.batteryDrained()` method that indicates if the battery is drained: + +```java +int speed = 5; +int batteryDrain = 2; +var car = new NeedForSpeed(speed, batteryDrain); +car.drive(); + +car.batteryDrained(); +// => false +``` + +## 5. Create the Nitro remote control car + +The best-selling remote control car is the Nitro, which has a stunning top speed of 50 meters with a battery drain of 4%. Implement the (static) `NeedForSpeed.nitro()` method to return this type of car: + +```java +var car = NeedForSpeed.nitro(); +car.drive(); +car.distanceDriven(); +// => 50 +``` + +## 6. Check if a remote control car can finish a race + +To finish a race, a car has to be able to drive the race's distance. This means not draining its battery before having crossed the finish line. Implement the `RaceTrack.tryFinishTrack()` method that takes a `NeedForSpeed` instance as its parameter and returns `true` if the car can finish the race; otherwise, return `false`. To see if the car can finish the race, you should try to drive the car until either you reach the end of the track or the battery drains: + +```java +int speed = 5; +int batteryDrain = 2; +var car = new NeedForSpeed(speed, batteryDrain); + +int distance = 100; +var race = new RaceTrack(distance); + +car.distanceDriven() +// => 0 + +race.tryFinishTrack(car); +// => true + +car.distanceDriven() +// => 100 + +## Source + +### Created by + +- @ystromm + +### Contributed to by + +- @mirkoperillo \ No newline at end of file diff --git a/need-for-speed/build.gradle b/need-for-speed/build.gradle new file mode 100644 index 0000000..8bd005d --- /dev/null +++ b/need-for-speed/build.gradle @@ -0,0 +1,24 @@ +apply plugin: "java" +apply plugin: "eclipse" +apply plugin: "idea" + +// set default encoding to UTF-8 +compileJava.options.encoding = "UTF-8" +compileTestJava.options.encoding = "UTF-8" + +repositories { + mavenCentral() +} + +dependencies { + testImplementation "junit:junit:4.13" + testImplementation "org.assertj:assertj-core:3.15.0" +} + +test { + testLogging { + exceptionFormat = 'full' + showStandardStreams = true + events = ["passed", "failed", "skipped"] + } +} diff --git a/need-for-speed/build/classes/java/main/NeedForSpeed.class b/need-for-speed/build/classes/java/main/NeedForSpeed.class new file mode 100644 index 0000000..c5098b7 Binary files /dev/null and b/need-for-speed/build/classes/java/main/NeedForSpeed.class differ diff --git a/need-for-speed/build/classes/java/main/RaceTrack.class b/need-for-speed/build/classes/java/main/RaceTrack.class new file mode 100644 index 0000000..79a442b Binary files /dev/null and b/need-for-speed/build/classes/java/main/RaceTrack.class differ diff --git a/need-for-speed/build/classes/java/test/NeedForSpeedTest.class b/need-for-speed/build/classes/java/test/NeedForSpeedTest.class new file mode 100644 index 0000000..93b52cd Binary files /dev/null and b/need-for-speed/build/classes/java/test/NeedForSpeedTest.class differ diff --git a/need-for-speed/build/reports/tests/test/classes/NeedForSpeedTest.html b/need-for-speed/build/reports/tests/test/classes/NeedForSpeedTest.html new file mode 100644 index 0000000..3198f31 --- /dev/null +++ b/need-for-speed/build/reports/tests/test/classes/NeedForSpeedTest.html @@ -0,0 +1,161 @@ + + + + + +Test results - Class NeedForSpeedTest + + + + + +

Their literals have single quotes e.g. `'A'`. + +Java `char`s support Unicode encoding so in addition to the Latin character set +pretty much all the writing systems in use worldwide can be represented, +e.g. the Greek letter `'β'`. + +There are many builtin library methods to inspect and manipulate `char`s. These +can be found as static methods of the `java.lang.Character` class. + +`char`s are sometimes used in conjunction with a `StringBuilder` object. +This object has methods that allow a string to be constructed +character by character and manipulated. At the end of the process +`toString` can be called on it to output a complete string. + +## Instructions + +In this exercise you will implement a partial set of utility routines to help a developer +clean up SqueakyClean names. + +In the 4 tasks you will gradually build up the `clean` method. +A valid SqueakyClean name is comprised of zero or more letters and underscores. + +In all cases the input string is guaranteed to be non-null. Note that the `clean` method should treat an empty string as valid. + +## 1.

These cases are structured to +support a useful process known as +[test-driven development (TDD)](https://en.wikipedia.org/wiki/Test-driven_development). +TDD involves repeating a structured cycle that helps programmers build complex +functionality piece by piece rather than all at once. That cycle can be +described as follows: + +1. Add a test that describes one piece of desired functionality your code is +currently missing. +2. Run the tests to verify that this newly-added test fails. +3. Update your existing code until: + - All the old tests continue to pass; + - The new test also passes. +4. [Clean up](https://en.wikipedia.org/wiki/Code_refactoring) your code, making +sure that all tests continue to pass. This typically involves renaming +variables, removing duplicated chunks of logic, removing leftover logging, etc. +5. Return to step 1 until all desired functionality has been built! + +The test files in this track contain _all_ the tests your solution should pass +to be considered valid. That doesn't immediately seem to be compatible with the +cycle described above, in which tests are written one by one. However, the +tool that we use to write our tests, [JUnit](http://junit.org), provides an +[@Ignore](http://junit.sourceforge.net/javadoc/org/junit/Ignore.html) +[annotation](https://docs.oracle.com/javase/tutorial/java/annotations/) that +can be used to temporarily skip an already-written test. Using this annotation, +we make sure that the test files we deliver to you satisfy the following rules: + +- The first test in any test file is _not_ skipped by default. +- All but the first test in any test file _are_ skipped by default. + +This allows you to simulate the TDD cycle by following these slightly-modified +steps: + +1. Run the tests to verify that _at most one_ test currently fails. +2. Update your existing code until all the non-skipped tests pass. +3. Clean up your code, making sure that all non-skipped tests continue to pass. +4. Remove the topmost `@Ignore` annotation in the test file. +5.
