java 实例 登录用户 equals的用法

import java.util.Scanner;

public class login {
    public static void main(String[] args) {
        String name, password;
        int i = 1;
        Scanner input = new Scanner(System.in);
        while (i <= 3) {
            System.out.println("请输入用户名");
            name = input.nextLine();
            System.out.println("请输入密码");
            password = input.nextLine();
            if (name.equals("yyy") && password.equals("a123456")) {
                System.out.println("WELCOME:" + name);
                System.out.println("你已经成功登陆！");
                break;
            } else {
                System.out.println("您输入的密码有误，请重新输入.");
                i++;
            }
        }
        if (i > 3) {
            System.out.println("你输入的次数已经超过限制，请明天再来输入");
        }
    }
}
