public class JavaApplication {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        System.out.println("Modulus of the no is:");

        int age = 50;
        double old_age = 32;

        System.out.println("age mod 10 = " + age % 10);
        System.out.println("old_age mod 10 = " + old_age % 10);

    }

}


output:

run:
Modulus of the no is:
age mod 10 = 0
old_age mod 10 = 2.0
