编写一个程序,模拟学校多个学生注册交学费流程。系统用户有学生、老师两类: (1)注册信息包括:学号、姓名、所属学院、专业、年级、班、宿舍。 缴费信息包括:学号、学期(例如:2022-2022-2)、学费、住宿费。 (2)功能需求:创建学生、老师两个子线程 1)学生线程实现注册、缴费; 2)老师线程统计不同学院的学费收缴金额、住宿费收缴金额。 (3)数据组织及存储要求 1)注册信息、缴费信息存储在.txt文件中; 2)注册、缴费信息要求使用泛型集合方式,具体实现类型自定; (4)测试数据要求: 1)存储注册信息的文件,至少有10条数据,至少涵盖2个学院、4个专业(不同专业对应的学费不同)。 2)存储缴费信息的文件,至少有10条数据,与注册信息关联。例如,某学生完成了注册,缴费,则在注册信息文件与缴费信息文件中新增两条信息,这两条信息有相同的学号。应Java写完整的代码,具体要求你定

好的,我根据你的要求编写了Java代码,如下所示:
Student.java
```java
public class Student {
private String id; // 学号
private String name; // 姓名
private String college; // 所属学院
private String major; // 专业
private String grade; // 年级
private String clazz; // 班级
private String dormitory; // 宿舍
public Student(String id, String name, String college, String major, String grade, String clazz, String dormitory) {
this.id = id;
this.name = name;
this.college = college;
this.major = major;
this.grade = grade;
this.clazz = clazz;
this.dormitory = dormitory;
}
public String getId() {
return id;
}
public String getName() {
return name;
}
public String getCollege() {
return college;
}
public String getMajor() {
return major;
}
public String getGrade() {
return grade;
}
public String getClazz() {
return clazz;
}
public String getDormitory() {
return dormitory;
}
@Override
public String toString() {
return id + "," + name + "," + college + "," + major + "," + grade + "," + clazz + "," + dormitory;
}
}
```
Teacher.java
```java
public class Teacher {
private String id; // 工号
private String name; // 姓名
private String college; // 所属学院
public Teacher(String id, String name, String college) {
this.id = id;
this.name = name;
this.college = college;
}
public String getId() {
return id;
}
public String getName() {
return name;
}
public String getCollege() {
return college;
}
@Override
public String toString() {
return id + "," + name + "," + college;
}
}
```
Payment.java
```java
public class Payment {
private String id; // 学号
private String term; // 学期
private double tuition; // 学费
private double accommodationFee; // 住宿费
public Payment(String id, String term, double tuition, double accommodationFee) {
this.id = id;
this.term = term;
this.tuition = tuition;
this.accommodationFee = accommodationFee;
}
public String getId() {
return id;
}
public String getTerm() {
return term;
}
public double getTuition() {
return tuition;
}
public double getAccommodationFee() {
return accommodationFee;
}
@Override
public String toString() {
return id + "," + term + "," + tuition + "," + accommodationFee;
}
}
```
RegistrationSystem.java
```java

}
System.out.println("学费收缴情况:");

System.out.println(college + ":" + collegeTuition.get(college));
}

}
// 查找学生所属学院
private String findCollege(String id) {

}
}
return null;
}
// 保存学生信息
public void saveStudents(String fileName) {

}
public static void main(String[] args) {
RegistrationSystem system = new RegistrationSystem();
// 加载测试数据
system.loadStudents("students.txt");
system.loadPayments("payments.txt");
// 创建学生、老师两个子线程
Thread studentThread = new Thread(() -> {
system.studentThread();

Thread teacherThread = new Thread(() -> {
system.teacherThread();
});
// 启动子线程
studentThread.start();
teacherThread.start();
try {
// 等待子线程结束
studentThread.join();
teacherThread.join();
} catch (InterruptedException e) {
e.printStackTrace();
}
// 保存数据
system.saveStudents("students.txt");
system.savePayments("payments.txt");
}
}
```
其中,students.txt和payments.txt是存储测试数据的文件。其他的代码注释中已经说明了。你可以根据自己的需求进行修改和扩展。
