This is a beginner's coding question.

package ex03;

public class Student extends Person {

public int number;

public Student(String name, int age, int number) {

    this.number=number;
}


public static void main(String[] args) {


    Student stu1 = new Student ("Jonghak Yoon", 13,20140112);



    System.out.println(stu1.getName());
    System.out.println(stu1.getage());
    System.out.println(stu1.number());

}

}

It's good to inherit the name and age from person, but I want to add the number inside and pull it together, but the method number is not defined in the bottom output of stu1.number... What's the problem? I've set up the get set and pulled it out. It's going well. But I wanted to do it without getting set...
