一、选题与前期调查
1.选题
学生基本信息管理系统(2人)等级:C-
功能要求:
1、添加学生功能:学号、姓名、性别、出生日期、政治面貌、家庭住址、电话、宿舍号。
2、根据学号查找学生信息:输入学号,根据学号查找学生的信息,查找不到则返回查找失败。
3、删除学生信息:根据输入的学号查找到该学生相应信息并且删除。
4、修改学生信息:根据输入的学号找到该学生相应信息,并且自主选择要修改的信息条目。
5、读取文件并存入文件:初始信息会从文件中读取,修改的信息也会写入文件。
6、GUI:使用GUI界面进行操作。
2.前期调查
使用gpt完成选题的研究。

5.文件
package storage;

public class StudentDataStorage {
private final String fileName; // 文件名,用于存储和读取学生数据
// 构造函数,初始化数据存储时要使用的文件名

this.fileName = fileName;
}
// 从文件中加载学生列表
public List<Student> loadStudents() {
List<Student> students = new ArrayList<>(); // 创建学生列表
try (BufferedReader reader = new BufferedReader(new FileReader(fileName))) {
String line;
while ((line = reader.readLine()) != null) { // 逐行读取
Student student = parseStudent(line); // 将每行文本解析为学生对象
if (student != null) {
students.add(student); // 添加到学生列表
}
}
} catch (IOException e) {
e.printStackTrace(); // 打印异常堆栈信息
}
return students; // 返回学生列表
}
// 将学生列表保存到文件
public void saveStudents(List<Student> students) {
try (PrintWriter out = new PrintWriter(new FileWriter(fileName))) {
for (Student student : students) { // 遍历学生列表
out.println(studentToFileString(student)); // 将每个学生对象转换为文本行并写入文件
}
} catch (IOException e) {
e.printStackTrace(); // 打印异常堆栈信息
}
}
// 将一行文本解析为学生对象
private Student parseStudent(String line) {
try {
String[] parts = line.split("\t"); // 假设使用制表符作为分隔符
// 解析学生信息的各个部分
String studentId = parts[0];
String name = parts[1];
String gender = parts[2];
String birthDate = parts[3];
String politicalStatus = parts[4];
String address = parts[5];
String phone = parts[6];
String dormitoryNumber = parts[7];
// 创建并返回学生对象
return new Student(studentId, name, gender, birthDate, politicalStatus, address, phone, dormitoryNumber);
} catch (Exception e) {
e.printStackTrace(); // 打印异常堆栈信息
return null; // 在解析出错时返回null
}
}
// 将学生对象转换为一行文本
private String studentToFileString(Student student) {
// 使用制表符分隔学生信息,并返回合成的字符串
return student.getStudentId() + "\t" +
student.getName() + "\t" +
student.getGender() + "\t" +
student.getBirthDate() + "\t" +
student.getPoliticalStatus() + "\t" +
student.getAddress() + "\t" +
student.getPhone() + "\t" +
student.getDormitoryNumber();
}
}
七、使用git管理代码
仓库地址:GitHub - 1726249845/mine
八、遇到的困难
添加修改,删除学生信息后表格内容不更新
解决方法:每次修改表格内容后重新载入表格
