Class LinkedEmployee has methods getPtr() and setPtr(). The class also has a standard enterEmployee() method. Fred has written code that sets up 3 LinkedEmployee objects using the code below. Add code that links them into a linked list. Be sure to set up head so that the linked list can be accessed. You can hardwire the linking; you dont need to use a loop to construct the linked list.

LinkedEmployee first = LinkedEmployee.enterEmployee();

LinkedEmployee second = LinkedEmployee.enterEmployee();

LinkedEmployee third = LinkedEmployee.enterEmployee();
