一、 java运算
通过异或运算符实现两个变量的互换
import java.util.Scanner;
public class ExchangeValueDemo
{
public static void main(String[] args)
{
try (Scanner scan = new Scanner(System.in)) {
System.out.println("请输入A的值:");
long A =scan.nextLong();//接收第一个变量值
System.out.println("请输入变量B的值:");
long B = scan.nextLong();//接收第二个变量
System.out.println("A="+A+"\tB="+B);
System.out.println("\t执行变量互换...\t");
A=A^B;
B=B^A;
A=A^B;
System.out.println("A="+A+"\tB="+B);
}
}
}
