// Correct code to count number
// of employees excluding interns.
 
class Employee {
   
    private int ID;
    private String name;
    private int age;
    private static int nextId = 1;
   
    // it is made static because it
    // is keep common among all and
    // shared by all objects
    public Employee(String name, int age)
    {
        this.name = name;
        this.age = age;
        this.ID = nextId++;
    }
    public void show()
    {
        System.out.println("Id=" + ID + "\nName=" + name
                           + "\nAge=" + age);
    }
    public void showNextId()
    {
        System.out.println("Next employee id will be="
                           + nextId);
    }
    protected void finalize()
    {
        --nextId;
        // In this case,
        // gc will call finalize()
        // for 2 times for 2 objects.

public class UseEmployee {
