Swap two number using bit operator

Swap two number using bitwise operator.

We use  ^ (XOR) operator for this.

public class SwapNumberUsingBitOperator {

public static void main(String[] args) {
int i=9;
int j=4;
System.out.println("Before swap i="+i+"j="+j);
i=i^j;
j=i^j;
i=i^j;
System.out.println("After Swap i="+i+"j="+j);
}

}
