java写一个学生类包含属性有学号性别姓名年龄 实现操作增加一个学生

下面是一个Java实现的学生类，包含属性：学号、性别、姓名、年龄，以及实现的操作：增加一个学生。

public class Student {
    private String id;      // 学号
    private String gender;  // 性别
    private String name;    // 姓名
    private int age;        // 年龄
    
    // 构造方法
    public Student(String id, String gender, String name, int age) {
        this.id = id;
        this.gender = gender;
        this.name = name;
        this.age = age;
    }
    
    // getter和setter方法
    public String getId() {
        return id;
    }
    public void setId(String id) {
        this.id = id;
    }
    public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    
    // 增加一个学生
    public static void addStudent(List<Student> students, Student student) {
        students.add(student);
    }
}

使用示例：

public class Main {
    public static void main(String[] args) {
        List<Student> students = new ArrayList<>();
        
        // 增加一个学生
        Student student = new Student("001", "男", "张三", 20);
        Student.addStudent(students, student);
        
        // 输出学生列表
        for (Student s : students) {
            System.out.println(s.getId() + " " + s.getGender() + " " + s.getName() + " " + s.getAge());
        }
    }
}
