Ha, ha, that's a good one if you're being sarcastic. If not then if an
employee is fired then you simply delete his/her instance in your code (it's
called an object's life cycle) or if you want, you can change his instance
to a person depending on the context of your system/application but you'll
have to get rid of the id attribute. Classes and objects are not the same
thing. This isn't a database and besides nic fuhrer says this thread of
discussion should cease.

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);
}
}
