实例009-不借助第3个变量实现2个变量的互换

代码如下：

public class ExchangeValue {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.println("input a:");
        long a = scan.nextLong();
        System.out.println("input b:");
        long b = scan.nextLong();
        System.out.println("a="+a+"\tb="+b);
        System.out.println();
        a=a^b;
        b=b^a;
        a=a^b;
        System.out.println("a="+a+"\tb="+b);
    }
}

结果如下：

input a:
22
input b:
11
a=22	b=11

a=11	b=22
