Modulo or Remainder Operator in Java

• Difficulty Level : Easy
• Last Updated : 03 Feb, 2021

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 %.

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:

Java

 // Implementation of Modulo or Remainder Operator in Javaimport 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);    }}
Output
7

Time Complexity :

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