我的调试和测试过程：
一．源代码如下
public class Admin extends User {
public Admin(String name, String call, int age, String sex,
String loginname, String password, String school) {
super(name, call, age, sex, loginname, password, school);
}
}
public class Student extends User {
public Student(String name, String call, int age, String sex,
String loginname, String password, String school) {
super(name, call, age, sex, loginname, password, school);
}
}
public class Teacher extends User {
public Teacher(String name, String call, int age, String sex,
String loginname, String password, String school) {
super(name, call, age, sex, loginname, password, school);
}
}
public class Test {
public static void main(String[] args) {
UI test=new UI();}
}

frame.addWindowListener(new WindowAdapter() {

}
});
button3.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
Login();
}
});
button4.addActionListener(new ActionListener() {

System.exit(0);
}
});
}
private void Login() {
User u1 = new Teacher("甲", "管理员", 45, "男", "1001", "007", "齐鲁工业大学");
User u2 = new Student("乙", "老师", 35, "男", "1002", "008", "齐鲁工业大学");
User u3 = new Admin("丙", "同学", 20, "男", "1003", "009", "齐鲁工业大学");

}
}

this.call = call;
this.age = age;

this.passWord = password;
this.school = school;
this.sex = sex;
}
public String read() {
return "欢迎" + call + "登录图书馆\n" + "\n" + "个人资料如下\n" + "姓名:" + name
+ "\n" + "年龄:"+ "性别:" +sex + age + "\n" + "学校:" + school;
}
}
二：程序中的错误代码都已被我们团队成功改正，我将着重展示测试结果：
代码的调试和测试过程都已成功展示，大家可以运行代码经行调试，有什么意见可以反馈给我。
