Java Program Example on Swap Numbers

Swap Numbers Java Example
This Swap Numbers Java Example shows how to swap value of two numbers using java.

 
 public class SwapElementsExample {  
     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);  
         //swap the value  
         swap(num1, num2);  
     }  
     private static void swap(int num1, int num2) {  
         int temp = num1;  
         num1 = num2;  
         num2 = temp;  
         System.out.println("After Swapping");  
         System.out.println("Value of num1 is :" + num1);  
         System.out.println("Value of num2 is :" +num2);  
     }  
 }  
   

Output of Swap Numbers example would be
Before Swapping
Value of num1 is :10
Value of num2 is :20
After Swapping
Value of num1 is :20
Value of num2 is :10
