swaping of two numbers using only TWO Variables

SOURCE : SwapUsingTwoVariable.java

public class SwapUsingTwoVariable {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		
		SwapUsingTwoVariable swap =  new SwapUsingTwoVariable();
		swap.numberswap(25,32);
		
		swap.numberp(34,76);

	}

	private void numberp(int i, int j) {
		
		System.out.println("number before swap " + i+ " "+j);
		i=i^j;
		j=i^j;
		i=i^j;
		
		
		System.out.println("number after swap   " + i+ " "+j )  ;
		
	}

	private void numberswap(int num1,int num2){
		
		System.out.println("number before swap " + num1+ " "+num2);
		num1=num1+num2;
		num2=num1-num2;
		num1=num1-num2;
		
		
		System.out.println("number after swap   " + num1+ " "+num2 )  ;
		
		
	}

}

INPUT
