Java has one important arithmetical operator you may not be familiar with, %, also known as the modulus or remainder operator. The % operator returns the remainder of two numbers. For instance 10 % 3 is 1 because 10 divided by 3 leaves a remainder of 1. You can use % just as you might use any other more common operator like + or -.

class Remainder {

  public static void main (String args[]) {

    int i = 10;
    int j = 3;
    int k;

    System.out.println("i is " + i);
    System.out.println("j is " + j);
  
    k = i%j;
    System.out.println("i%j is " + k);
  }

}
