Hi Hari Sir,
Thank You very much for your real time example on collection framework.
I have Developed the code according your requirement and its working.

import java.util.ArrayList;
import java.util.List;

public class FrontOfficePeople {

public static void main(String[] args) {

Company company = new Company();

company.createEmployee(101, "Hari", 50000, "Software Engg");
company.createEmployee(102, "Naresh", 40000, "Manager");
company.createEmployee(103, "Mahesh", 30000, "Testing Engg");
company.createEmployee(104, "Kiran", 35000, "Java Developer");

List<Employee> list = company.getEmployeesList();

for (Employee emp : list) {
System.out.println(emp);
}

}

}

class Employee {

private int empNo;
private String empName;
private int salary;
private String job;

public Employee(int empNo, String empName, int salary, String job) {
this.empNo = empNo;
this.empName = empName;
this.salary = salary;
this.job = job;
}

public String toString() {
return empNo + " " + empName + " " + salary + " " + job;
}

}

class Company {
private Employee employee;
private List<Employee> list;

public Company() {
list = new ArrayList<Employee>();
}

public void createEmployee(int empNo, String empName, int salary, String job) {
employee = new Employee(empNo, empName, salary, job);
list.add(employee);
}

public List<Employee> getEmployeesList() {
return list;
}

}

the first rule of teaching is that you have to connect wid the students so that they correlate wid topic and you are master in that
the way you explain the topic is simply amazing.thanks sir for making collection so easy i hope one day i m also master in collection only bcoz of you
