# Raindrops
|
||
|
|
|
||
|
|
Welcome to Raindrops on Exercism's Java Track.
|
||
|
|
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
|
||
|
|
Your task is to convert a number into a string that contains raindrop sounds corresponding to certain potential factors. A factor is a number that evenly divides into another number, leaving no remainder. The simplest way to test if a one number is a factor of another is to use the [modulo operation](https://en.wikipedia.org/wiki/Modulo_operation).
|
||
|
|
|
||
|
|
The rules of `raindrops` are that if a given number:
|
||
|
|
|
||
|
|
- has 3 as a factor, add 'Pling' to the result.
|
||
|
|
- has 5 as a factor, add 'Plang' to the result.
|
||
|
|
- has 7 as a factor, add 'Plong' to the result.
|
||
|
|
- _does not_ have any of 3, 5, or 7 as a factor, the result should be the digits of the number.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
- 28 has 7 as a factor, but not 3 or 5, so the result would be "Plong".
|
||
|
|
- 30 has both 3 and 5 as factors, but not 7, so the result would be "PlingPlang".
|
||
|
|
- 34 is not factored by 3, 5, or 7, so the result would be "34".
