โจทย์ฝึกหัด อันนี้ไม่ต้องส่ง แต่ต้องทำให้ถูกนะ

A a class – Human - already has the following code:

public class Human{

            private int life;

            private Human[] relatives;

}

 
1. Write methods for getting and setting a human’s life respectively.
2.  Write a constructor for the class Human. The constructor receives 2 arguments, and set the human’s two variables respectively.

3.    3. write a class Test. This class has a main method that creates a Human with the life being 2 and the relatives being null. Then the main method sets its life to 5.
