Java Program Example on Swap Numbers Without Using Third Variable

Swap Numbers Without Using Third Variable Java Example
This Swap Numbers Java Example shows how to swap value of two numbers without using third variable using java.

 
 public class SwapElementsWithoutThirdVariableExample {  
     public static void main(String[] args) {  
         int num1 = 10;  
         int num2 = 20;  
         System.out.println("Before Swapping");  
         System.out.println("Value of num1 is :" + num1);  
         System.out.println("Value of num2 is :" +num2);  
         //add both the numbers and assign it to first  
         num1 = num1 + num2;  
         num2 = num1 - num2;  
         num1 = num1 - num2;  
         System.out.println("Before Swapping");  
         System.out.println("Value of num1 is :" + num1);  
         System.out.println("Value of num2 is :" +num2);  
     }  
 }  
  

Output of Swap Numbers Without Using Third Variable example would be
Before Swapping
Value of num1 is :10
Value of num2 is :20
Before Swapping
Value of num1 is :20
Value of num2 is :10
