Create a single linked list class named SLList that provides the following methods:

void add( E item )	Add item at the tail of the list
E get( int index )	Return object E at position index in list If index out of bounds, return null
int indexOf( E target )	Return index of target in the linked list If found, return the index (relative 0) If not found, return -1
int size()	Return number of items in list

You will need the appropriate constructors. In addition, you may also implement other methods that may be useful for the assignment. Thoroughly test all of the methods with a simple test class before using the linked list to complete the assignment. Once the SLList class has been successfully tested, proceed with developing the application below.

Develop a menu-driven system that maintains a list of employees. Name the client program Prog3.java and the menu class EmpMenu.java. The program should begin by calling the EmpMenu class constructor which will load the linked list. The constructor will read the employee.txt file, create an Employee object for each record in the file, and load the Employee object into the SLList single linked list. The program will continue by displaying a menu for the user.

employee.txt file: CSV (comma separated value) text file in which each line in the file represents an employee. The comma delimited fields are:

Fields	Description
Employee ID	string
First Name	string
Last Name	string
Salary	double

A menu will then be displayed, allowing the user the following options:

1. Display	Display all employees in list in easy to read tabular format
2. Add employee	Get employee information from user and add to tail of list
3. Find employee	Get employee ID from user If found, display employee information in easy to read format If not found, display message
0. Exit	Do I really need to explain this???

After performing the appropriate action, display a new menu and repeat until user selects the exit option.
