Given/input two values, we have to find the remainder without using modulus (%) operator.
Submitted by Nidhi, on February 24, 2022

Problem statement

In this program, we will read two integer numbers from the user and find the remainder without using the modulus "%" operator.

Source Code

The source code to find remainder without using the modulus '%' operator is given below. The given program is compiled and executed successfully.

// Java program to find the remainder 
// without using the % operator

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner X = new Scanner(System.in);

    int num1 = 0;
    int num2 = 0;
    int rem = 0;

    System.out.printf("Enter first number: ");
    num1 = X.nextInt();

    System.out.printf("Enter second number: ");
    num2 = X.nextInt();

    rem = num1 - (num1 / num2) * num2;

    System.out.printf("Remainder is: %d", rem);
  }
}

Output

Enter first number: 21
Enter second number: 4
Remainder is: 1

Explanation

In the above program, we imported "java.util.Scanner" package to read input from the user. And, created a public class Main. It contains a static method main(). The main() method is an entry point for the program. Here, we read two integer numbers from the user. Then we find the remainder without using the "%" operator.
