package interview_programs;
public class Swapping {

    int x,y ;

    Swapping(int a, int b){ 
    int x = a;      
    int y = b;
    System.out.println("the valueof x is" + x);
    System.out.println("the valueof y is" + y);     
    }

    y = x - y;
    x = x - y;          
    System.out.println("the value after swap");
    System.out.println("the valueof x is" + x);
    System.out.println("the valueof y is" + y);             
    }   

    public static void main (String args[]) {   
    Swapping Swap = new Swapping(10,5);
    Swap.replace();
