Hints

General

• Numbers tutorial.

1. Calculate the production rate per second

• Determining the success rate can be done through a conditional statement.
• Java allows for multiplication to be applied to two different number types (such as an int and a double). It will automatically return the "broader" data type.
• Numbers can be compared using the built-in comparison and equality operators.

2. Calculate the number of working items produced per second

• Whereas an int can be automatically converted to a double, the reverse does not hold. The reason for this is that an int has less precision than a double so rounding has to be applied, also the range of numbers an int can represent is smaller than a double. To force this conversion you can use a cast to an int.
