        private String password;
        public User(String name, String password){
            this.name = name;

        }

        }
    }
    static class ManagementUser{
        public String CheakUser(User one,User two){
            if(one.getName().equals(two.getName())&one.getPassword().equals(two.getPassword()))
            {
                System.out.println("=======================");
                
            }else{
                System.out.println("=======================");
                System.out.println("两次输入代码不一致");
            }
            return null;
        }
    }
    // 测试方法
	public static void main(String[] args) {
     //实例化对象，调用相关方法实现运行效果
      User one = new User("luck","123456");
        User two = new User("Mike","123456");
        one.methods();
        two.methods();
        ManagementUser three = new ManagementUser();
        three.CheakUser(one,two);
    }
}
