In this Tutorial we are going to swap two variables without using temporary variable . Here swapping means, inter changing the value of two variables
public class SwapWithoutTemp{
public static void main(String[] args) {
int a= 10 , b =20;
a = a+b;
b = a-b;
a = a-b;
System.out.println("After Swapping a = "+a+" : b = "+b);
}
}
