Submitted by Nidhi, on February 23, 2022

Problem statement

In this program, we will read two integer numbers from the user and perform subtraction without using the minus (-) operator, and print the result.

Source Code

The source code to perform subtraction without using the Minus (-) operator is given below. The given program is compiled and executed successfully.

// Java program to perform subtraction 
// without using minus (-) 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 sub = 0;

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

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

    sub = num1 + ~num2 + 1;

    System.out.printf("Subtraction of %d-%d=%d", num1, num2, sub);
  }
}

Output

Enter first number: 65
Enter second number: 54
Subtraction of 65-54=11

Explanation

In the above program, we imported the "java.util.Scanner" package to read input from the user. Here, we 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 and performed the subtraction operation using "+" and "~" operators. After that, we printed the result.
