   // a simple class to store in the array
   public class Employee

      // a simple class to store in the array
      public Employee(int empID)

         Employee[] empArray;
         intArray = new int[5];
         empArray = new Employee[3];

         // populate the array
         for (int i = 0;i<empArray.Length;i++)
         {
            empArray[i] = new Employee(i+5);

Commented:
The class Employee is a class that just holds the employeeId (Which is an integer).

The tester class is the one that holds main.

Main creates 2 arrays, one of ints and the other of Employees.

Then it fills the employee array creating employees whose id is 5, 6 and 7 respectively.

After that it prints all the elements of the integer array (Which has not been initialized by the way).

and finally it prints all the elements of the Employee array.

The output of this final array would be

5, 6, 7

As the toString method of the employee class prints the EmployeeId.

Hope this helps
