This project simulates a remote procedure call on a client-server architecture.

You will create both the client and the server. The server will maintain a linked list. It must NOT use one of Java's collection classes (i.e. Vectors, ArrayList, etc), write your own linked list. Singly linked is fine.

The client will request various operations on the linked list. The communication between a client and a server is implemented through sockets. You will build both the server and the client. The server must be multithreaded. I do not specify a communication protocol, you can use your own.

The server:

1. The server will provide the following operations to the client:

• insert an integer to the end of a linked list (take one integer parameter)
• remove an integer from a linked list (take one integer parameter - the index into the list)
• get the number of integers in a linked list (No parameter)
• get the first integer in a linked list (No parameter)
• get the last integer in a linked list (No parameter)

2. The server uses semaphores to protect the linked list

3. The server is multithreaded (Ex: can handle multiple client connections).

The client:

1.       Display a menu to users and ask users to input parameters if any

• insert an integer to the end of a linked list
• remove an integer from a linked list given a particular index into the list
• get the number of integers in a linked list
• get the first integer in a linked list
• get the last integer in a linked list
• terminate the client

2.       Pack user's request as a message, which is sent to the server through a socket

3.       Unpack the result and display it to the user
