Java Program To Swap Two Values

import java.util.*;  
class SwapTheValues {  
    public static void main(String[] args) { 
     // x, y and temp variables
       int x, y, t;
       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( );  
    }    

Output:

before swapping numbers: 10 12

After swapping: 12 10
