Java program for subtraction of two number

Java program for subtraction two Integers

In this section, you will learn how to subtract two numbers in Java. Let's see :

1.) First program :

In this program, we specify the value of both the numbers in the program itself.

Let's try to create a simple example :

  ➤ Example : subtract two numbers with predefined value;

class SubtractTwoNumbers {
      public static void main(String[] args) {      
      int x = 15, y = 10, subtract;
      subtract = x - y;
      
      System.out.println("Subtraction of two numbers is : "+subtract);
   }
}

Explanation :

 Example 1 : explanation

In the above program, we have created three integer variables x, y and subtract, then stored (15 and 10) values in x and y.

• Then, x and y are subtract using the - operator, and its result is stored in another variable subtract.

• Finally, subtract is printed on the screen using System.out.println() function.

2.) Second program :

In this program, we will take two inputs from the user(entered by the user) and prints the subtract.

Note : Scanner class is a part of package(java.util), so we required to import this package in our Java program.

Let's try to create a simple example :

  ➤ Example : subtract two numbers with user input(Scanner);

import java.util.Scanner;
class SubtractTwoNumbers 
{
   public static void main(String args[]) {      
      int x, y, subtract;

      System.out.println("Enter two integers to calculate their subtraction : ");
      Scanner in = new Scanner(System.in);
     
      x = in.nextInt();
      y = in.nextInt();
      subtract = x - y;
     
     System.out.println("Subtraction of two numbers is : "+subtract);
   }
}

Explanation :

 Example 2 : explanation

In the above program, we have created three integer variables x, y and subtract, then create a Scanner class so that you can take input from the user for x and y.

• Then, x and y are subtract using the - operator, and its result is stored in another variable subtract.

• Finally, subtract is printed on the screen using System.out.println() function.
