Java로 간단한 학생 정보 관리 시스템을 작성하는 방법은 무엇입니까?

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.id = id;

       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;
   }
}
