JAVA实现两个变量间的互换

public class VaiableExchange {
       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("请输入变量B的值");
long B = scan.nextLong();
System.out.println("A="+A+"\tB="+B);
System.out.println("执行变量互换...");
A = A^B;
B = B^A;
A = A^B;
System.out.println("A="+A+"\tB="+B);
}
}
