public class SwapValueFromTwoVariablesWithoutTemporaryVariable {

	public static void main(final String[] args) {
		//
		int a = 10;
		//
		int b = 2;
		//
		System.out.println("a=" + a + ",b=" + b);
		//
		a = a + b;
		//
		System.out.println("a=" + a + ",b=" + b);
		//
		b = a - b;
		//
		System.out.println("a=" + a + ",b=" + b);
		//

		//
		System.out.println("a= " + a + ",b=" + b);
		//
	}

}

Output

a=10,b=2
a=12,b=2
a=12,b=10
a= 2,b=10
