Swapping with the third variable:-

Class mobile



{



public static void main(String args[]) 



{



int x = 10, int y = 21, int temp;



System.out.println("Before swapping "+x+", "+ + y);



temp=x;



x=y;



y=temp;



System.out.println("After swapping "+x+", "+ + y);



}



}



Output-



x=21



y=10.

Without third variable-



Class student



{



public static void main(String args[]) 



{



int x = 60;



 int y = 40;



System.out.println("Before swapping "+x+", "+ + y);



x=x+y;



y=x-y;



x=x-y;



System.out.println("After swapping "+x+", "+ + y);



}



}



Output-



x=40



y=60.
