Modulo or Remainder Operator in Java
• Difficulty Level : Basic
• 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 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);``    ``}``}`
Output
`7`

Time Complexity :

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