图中，Java子类如何继承

Question

类图，Person为类名，name,age为属性，name是String类型，age是int类型
Student类和Teacher类是Person类的子类
Person类中的move是成员方法，返回值为void，say()方法返回值为void，其他类同理

public class Test {
    public static void main(String[] args) {
        Student student=new Student("小白",18,"10001");
        Teacher teacher=new Teacher("张老师",32,"2001");
        System.out.println("学生姓名:"+student.getName());
        student.study();
        student.move();
        student.say();
        System.out.println("老师姓名:"+teacher.getName());
        teacher.teach();
        teacher.move();
        teacher.say();
    }
}

public class Person {
    protected String name;
    protected int age;
    public void move(){
        System.out.println("可以移动。。。");
    }
    public void say(){
        System.out.println("可以说话。。。");
    }
}

public class Student extends Person{
    private String studentNo;
    public Student(){}
    public Student(String name,int age,String studentNo){
       this.name=name;
       this.age=age;
       this.studentNo=studentNo;
    }
    public String getName(){
      return name;
    }
    public void study(){
        System.out.println("正在学习。。。");
    }
}

public class Teacher extends Person{
    private String teacherNo;
    public Teacher(){}
    public Teacher(String name,int age,String teacherNo){
       this.name=name;
       this.age=age;
       this.teacherNo=teacherNo;
    }
    public String getName(){
      return name;
    }
    public void teach(){
        System.out.println("正在教书。。。");
    }
}
