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);
    }
}
