Use the information above to complete these tasks
Use an Employee array to keep the references to all Employee objects created.
- Ask the user for the number of Employees to be processed. The Employee array needs to accommodate all data. For example, the user may want to create 10 employee's data. Your Employee array should be able to hold 10 Employee object references.
- Use a loop to ask employee data, initialize each element in the Employee array.
- After initializing all elements, print every Employee's information and eligibility for retirement.

import java.util.Scanner;
public class EmployeeApp {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name;
int age;
int yearsOfService;
int input = 0;
System.out.println("please enter number of Employees to be processed");
input=scan.nextInt();
Employee[] empArray = new Employee[input];
// a loop to take two employees data and create two Employee objects
for (int i = 0; i < empArray.length; i++)
{
// take user input
System.out.println("Enter an Employee's name");
name = scan.next();
System.out.println("Enter the age of the employee");
age=scan.nextInt();
System.out.println("Enter the Number of years of service");
yearsOfService =scan.nextInt();
empArray[i] = new Employee(name, age, yearsOfService);
}
System.out.println("Number of Employee Objects: " + Employee.numObj);
int count = 1;
for (Employee e : empArray)
{
System.out.println("Employee" + count + "'s name: " + e.getName());
System.out.println("Emp 1's eligibility for retirement: " + e.isEligibleForRetirement());
count++;
}
