Modulus Operator in Java: Explanation & Practice

Problem summary

Check if 17 is even or odd using the modulus operator.

Starter code

public class Main {
    public static void main(String[] args) {
        int number = 17;
        
        // Use modulus to find remainder when divided by 2
        // Print: Number: 17
        // Print: Remainder when divided by 2: 1
        // Print: Is odd: true
    }
}

Expected output and test cases

• Check if 17 is odd

  Number: 17
  Remainder when divided by 2: 1
  Is odd: true

Hints

1. The % operator gives the remainder of division
2. number % 2 gives 0 for even, 1 for odd
3. Compare remainder != 0 to check if odd
