Using Iterator and Enumeration on a Vector of Employee Objects in Java

The following example code demonstrates a program Using Iterator and Enumeration on a Vector of Employee Objects in Java.

Here’s an example of using Iterator and Enumeration for a Vector of Employee objects in Java.

import java.util.*;

class Employee {
  private String name;
  private int age;

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

  public String toString() {
    return name + ", " + age;
  }
}

public class Main {
  public static void main(String[] args) {
    Vector<Employee> employees = new Vector<>();
    employees.add(new Employee("John Doe", 30));
    employees.add(new Employee("Jane Doe", 25));
    employees.add(new Employee("Jim Smith", 35));

    // Using Iterator
    Iterator<Employee> it = employees.iterator();
    System.out.println("Using Iterator:");
    while (it.hasNext()) {
      Employee employee = it.next();
      System.out.println(employee);
    }

    // Using Enumeration
    Enumeration<Employee> en = employees.elements();
    System.out.println("\nUsing Enumeration:");
    while (en.hasMoreElements()) {
      Employee employee = en.nextElement();
      System.out.println(employee);
    }
  }
}

This example defines a class Employee that has a name and age and creates a Vector of Employee objects. It then uses both Iterator and Enumeration to traverse the Vector and print the name and age of each Employee object.
