Hi,

And when the Employee get fired ? Do you change his/her class to make
him/her a Person ?

There's plenty of books, online documentation and courses for this.  Visit:
http://java.sun.com/docs/books/tutorial/java/index.html but an example
probably won't do it for you if you're not familiar with OOP.  Nonetheless,
below is an example of a Person object and an Employee object which inherits
from Person.

public class Person
{
    private String name;
    private int age;

    public Person()
    {
        this.name = "";
        this.age = 0;
    }

    public Person(
        String name,
        int age
        )
    {
        this.name = name;
        this.age = age;
    }

    public void setName(
        String name
        )
    {
        this.name = name;
    }

    public String getName()
    {
        return this.name;
    }

    public void setAge(
        int age
        )
    {
        this.age = age;
    }

    public int getAge()
    {
        return this.age;
    }
}

class Employee extends Person
{
    private int id;

    public Employee()
    {
        this.id = 0;
        super.setName("");
        super.setAge(0);
    }

    public Employee(
        int id,
        String name,
        int age
        )
    {
        this.id = id;
        super.setName(name);
        super.setAge(age);
    }

    public void setId(
        int id
        )
    {
        this.id = id;
    }

    public int getId()
    {
        return this.id;
    }

    public int calculateSalary()
    {
        return (this.id * 10000);
    }
}
