Modulo or Remainder Operator in Java

Modulo or Remainder Operator returns the remainder of the two numbers after division. If you are provided with two numbers, say A and B, A is the dividend and B is the divisor, A mod B is there a remainder of the division of A and B. Modulo operator is an arithmetical operator which is denoted by %.

NOTE:    If numerator is less than denominator then % will give output as the numerator only.

Syntax:

A % B
Where A is the dividend and B is divisor

Example:

Input : a = 15, b = 6 
// 15%6 means when we divide 15(numerator) by 6(denominator) we get remainder 3// 
Output: 3
Input : a = 16, b = 4 
Output: 0

Approach:

1. Take Dividend and Divisor from the user.
2. Create an integer variable and assign it with A % B expression.
3. Print that variable.

Below is the implementation of the above approach:

// Implementation of Modulo or Remainder Operator in Java
import java.io.*;
import java.util.*;

class GFG {
    public static void main(String[] args)
    {
        // Dividend
        int a = 15;

        // Divisor
        int b = 8;

        // Mod
        int k = a % b;
        System.out.println(k);
    }
}

Time Complexity : 

Modular function usually takes Constant time / O(1) time like other arithmetic operations.
