Java Program to Swap Two Numbers

You are currently viewing Java Program to Swap Two Numbers

Hey guys! If you are looking to know the concept of the “Java Program to Swap Two Numbers” then read this tutorial to learn about it. Initially, We will discuss the swapping numbers and how to do a task? Let’s see the possibilities here.

Interchanging the values of two variables with each other is called the swapping numbers. For example, If we can assign “a=2”, “b=4” then the output will be like “a=4”, “b=2”.

Java Program to Swap Two Numbers

We can swap two numbers using java in the below example program.

import java.util.*;  
class Swap_With {  
    public static void main(String[] args) {  
       int x, y, t;// x and y are to swap   
       Scanner sc = new Scanner(System.in);  
       System.out.println("Enter the value of X and Y");  
       x = sc.nextInt();  
       y = sc.nextInt();  
       System.out.println("before swapping numbers: "+x +"  "+ y);  
       /*swapping */  
       t = x;  
       x = y;  
       y = t;  
       System.out.println("After swapping: "+x +"   " + y);  
       System.out.println( );  
    }    
}  

Source Code Explanation

Initially, We have to import the java.util.scanner class into this program. Secondly, We need to declare the respective variables for both input and output values.

After running this program, The program asks you to enter the input values. The output of swapping numbers will be displayed on the output screen after applying the values and clicking on the enter button.

Finally, The system.out.printIn() function will help to show the result on the output screen.
