继承，子类，在 Java 中使用 super.print() 打印

我有4个不同的班级。一题Student，一Instructor，一Person和Main。下面是我的代码：

学生：

public class Student extends Person {
public void print() {
    super.print();
    System.out.println(", credits: " + credits);
}
}

讲师：

public class Instructor extends Person{
private double salary;
public double getSalary() {
    return salary;
}

public void setSalary(double newSalary) {
    salary = newSalary;
}

public void print() {
    super.print();
    System.out.println(", salary: " + salary);
}
}

人：

public class Person {

private String name;
private String id;

public String getName() {
return name;
}

public void setName(String replacementName) {
name = replacementName;
}

public String getID() {
return id;
}

public void setID(String id) {
this.id = id;
}

public void print() {
    System.out.print(name + ", student ID: " + id);
    }

}

主要的：

public class Main {

public static void main(String[] args) {
    Instructor instructor = new Instructor();
    instructor.setName("Hani Javadi");
    instructor.setID("888777666");
    instructor.setSalary(11111);
    instructor.print();

    System.out.println("--- --- ---");

    Student student1 = new Student();
    student1.setName("Joe Loop");
    student1.setID("810123456");
    student1.addCredits(10);
    student1.print();

    Student student2 = new Student();
    student2.setName("Mary Collection");
    student2.setID("811987321");
    student2.addCredits(25);
    student2.print();

    Student student3 = new Student();
    student3.setName("Ke Method");
    student3.setID("810010101");
    student3.print();
}

}

当我去输出这段代码时，结果是这样的：

Hani Javadi, student ID: 888777666, salary: 11111.0 

Joe Loop, student ID: 810123456, credits: 10

Mary Collection, student ID: 811987321, credits: 25 

Ke Method, student ID: 810010101, credits: 0

但是，输出需要有第一行：

Hani Javadi, instructor ID: 888777666, salary: 11111.0 

任何人都可以帮助解决这个微不足道的错误吗？我已经努力了几个小时，试图通过if在超类中添加一条语句来找到解决它的方法，Person但似乎没有任何效果。有没有一种简单的方法可以让教师打印声明来显示教师 ID 而不是学生 ID？
