Hey all,

Im new to java and to java forums and need a dig out with an assignment Im working on.

I have an Employee Class with data members such as name, age etc. What I am trying to do is give each employee an ID when they are created. This is working: heres some of the construcor code:

Code:

import java.io.*;
import java.util.*;

public class Employee implements Serializable{
	
	//data members
	protected String firstname;
	protected String surname;
	protected int age;
	protected char gender;
	protected double annualSalary;
	protected double bonus;
	protected int empID;
	protected static int noOfEmployees = 0;
	//public int ID;
	
	//constructors
	
	//default constructor
	public Employee(){
			 	
	}
	
	
	public Employee(String fName, String sName, int age1, char sex, double salary){
		
		firstname = fName;
		surname = sName;
		age = age1;
		gender = sex;
		annualSalary = salary;
		
		empID = ++noOfEmployees;
	}

The problem is arising in the main class. I am prompting users to enter employee details, which I am adding to an ArrayList employees. I then output them and the empID is incrementing properly.
I write them correctly to a .data file. When I read the array back, all the previously enterer employees are there but when I add more employees, the ID is starting again at 1.

Please suggest a way around this??
