package one;
//管理类
public class UserManager {

package one;
public class Test {
public static void main(String[] args) {
User one = new User("花花","123456");
User two = new User("凡凡","123456");
one.print();
two.print();
System.out.println("===============");
UserManager n = new UserManager();
n.check(one, two);
//System.out.println();

}
效果图
用户名：花花
密码：123456
用户名：凡凡
密码：123456
===============
