Java两个变量的互换(不借助第3个变量)具体实现方法

import java.util.Scanner;public class VariableExchange {    public static void main(String[] args){        System.out.println("请输入变量A的值");        Scanner scanner=new Scanner(System.in);        long A=scanner.nextLong();        System.out.println("请输入变量B的值");        Scanner scannerB=new Scanner(System.in);        long B=scannerB.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);    }}
