Person 클래스를 상속하는 Professor, Student, Staff 클래스를 만들자

package model;

public class Professor extends Person {
	String[] subjects;

	public Professor(int num, String name, String dept, String address, String[] subjects) {
		super(num, name, dept, address);
		this.subjects = subjects;
	}

	@Override
	public void print() {
		super.print();
		for(int i=0;i<subjects.length;i++) {
			System.out.println(subjects[i]);
		}
	}
		
}

package model;

public class Student extends Person {
	String[] subjects;

}

package model;

public class Staff extends Person {
	String job;

}
