Question

Write a method body for the static method isDivisibleBy5 shown below. The only NaturalNumber methods you are allowed to use are the kernel methods multiplyBy10, divideBy10, and isZero. For full credit, your method must use a single return statement and it must restore n without making any copies. No recursion is needed.

Answer 1

Answer:

public static boolean isDivisibleBy5(int number) {

       boolean isTrue = true;

       if (number % 5 == 0)

           isTrue = true;

       else

           isTrue = false;

           

       return isTrue;

   }

Explanation:

- Create a method called isDivisibleBy5 that takes one parameter, an integer number

- Inside the method, create a boolean variable, isTrue, that will be used to store the result

- Check if the number is divisible by 5, using the module operator. If it is, set the isTrue as true. Otherwise, set the isTrue as false

- Return the isTrue
