Java で簡単な学生情報管理システムを作成するにはどうすればよいですか?

public class Student {
   private String name;
   private int id;
   private String course;
   private int score;
  
   // 构造函数
   public Student(String name, int id, String course, int score) {
       this.name = name;
       this.id = id;
       this.course = course;
       this.score = score;
   }
  
   // 获取学生姓名
   public String getName() {
       return this.name;
   }
  
   // 获取学生学号
   public int getId() {
       return this.id;
   }
  
   // 获取学生课程
   public String getCourse() {
       return this.course;
   }
  
   // 获取学生成绩
   public int getScore() {
       return this.score;
   }
}

import java.util.ArrayList;

public class StudentManagementSystem {
   private ArrayList<Student> students;
  
   // 构造函数
   public StudentManagementSystem() {
       students = new ArrayList<>();
   }
  
   // 添加学生
   public void addStudent(Student student) {
       students.add(student);
   }
  
   // 根据学号查找学生
   public Student findStudentById(int id) {
       for (Student student : students) {
           if (student.getId() == id) {

       StudentManagementSystem system = new StudentManagementSystem();
      
       // 添加一些学生

       system.addStudent(new Student("李四", 1002, "Python编程", 90));
       system.addStudent(new Student("王五", 1003, "C++编程", 85));
      
       // 查找学生
       Student student1 = system.findStudentById(1002);
       System.out.println(student1.getName() + " " + student1.getCourse() + " " + student1.getScore());
