package 实现两个变量的互换;


import java.util.Scanner;

public class 实现两个变量的互换 {
    public static void main(String[] args)
    {
        Scanner scan = new Scanner(System.in);
        
        System.out.println("请输入变量 A 的值:");
        long A = scan.nextLong();
        
        System.out.println("请输入 B 的值:");
        long B = scan.nextLong();
        
        System.out.println("A ="+A+"\t B ="+B);
        
        System.out.println("执行变量互换");
        
        A = A^B;
        B = B^A;
        A = A^B;
        
        System.out.println("A ="+A+"\t B ="+B);
    }
