今天学习基础，本人小萌新，发表一点今天联系的代码，继续加油。
public class Person {
    private String name;
    private String gender;
    private int age;
    private String nationality;

    public void eat(){
        System.out.println("吃饭");
    }
    public void sleep(){
        System.out.println("睡觉");
    }
    public void work(){
        System.out.println("工作");
    }

}
public class Student extends Person {
    private String school;
    private int stuNumber;

    public Student() {
    }

    public Student(String name, String gender, int age, String nationality) {
    }

    @Override
    public void work() {
        System.out.println("学生需要学习！");
    }

}
public class StudentLeader extends Student {
    private String jod;

    public StudentLeader(){}
    public StudentLeader(String name, String gender, int age, String nationality){
    }

    public void meeting(){
        System.out.println("学生干部喜欢开会！");
    }
}
public class Test {
    public static void main(String[] args) {
        Student s = new Student();
        s.work();

        Worker w = new Worker();
        w.work();

        StudentLeader sL = new StudentLeader();
        sL.meeting();
    }
}
就是这些了，继续努力
