Question

Write a public method called containsDivPair that:

• accepts three integer parameters

• returns true if any two of the numbers are divisible by 5, false otherwise

Answer 1

public static boolean containsDivPair(int n1, int n2, int n3) {
    return n1 % 5 == 0 && n2 % 5 == 0 || n1 % 5 == 0 && n3 % 5 == 0 || n2 % 5 == 0 && n3 % 5 == 0;
}

public class DivPair {

    public static boolean containsDivPair(int n1, int n2, int n3) {
        return n1 % 5 == 0 && n2 % 5 == 0 || n1 % 5 == 0 && n3 % 5 == 0 || n2 % 5 == 0 && n3 % 5 == 0;
    }

    public static void main(String[] args) {
        System.out.println(containsDivPair(5, 10, 15));
        System.out.println(containsDivPair(5, 12, 15));
        System.out.println(containsDivPair(5, 10, 11));
        System.out.println(containsDivPair(5, 12, 17));
    }
}
