UserManager不应该同时传递用户名和密码，一共四个值吗

那在test.java当中如何讲用户名和密码两个值都封在User One一个值上面呢 import java.util.Scanner; public class Test{ // 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 Scanner sc = new Scanner(System.in); System.out.print("用户名："); String userOne = sc.next(); System.out.print("密码："); String passwordOne = sc.next(); System.out.print("用户名："); String userTwo = sc.next(); System.out.print("密码："); String userTwo = sc.next(); System.out.println("==================="); UserManage um = new UserManager(); um.CheckUser(userOne, userTwo); } }
