Java based Multi-threaded File server Application meant to satisfy multiple client requests through socket connections/request

Working principle :

Multiple clients talk to a single server through common/ constant port number (in a network, a port binding), each client request serves as a new server connection (aka a client handler), on every new client request invocation the main thread at the server starts a new worker thread through start method thus calls run method implemented via Runnable interface. Thus server serves the client request through a separate server connection thread and creates a new socket connection.

Tasks : client may invoke two operations: index and get "filename.txt".

index should return the total available files stored at the server, in this project these files are stored in a folder called "files", namely two files , names.txt and companies.txt : return these file names.

upon invocation by a client program "get names.txt" operation server should not only send back an OK messages but its content as well.

Data transfer mechanism :

using input and output streams between both client and the server, data is flushed and sent to-and-fro over the network.

How to Run:

Goto the package com.fileserverapp.server (located inside src/main/java folder) and select MultiThreadedFileServer.java(this is our server, which is has to be run first), run in the eclipse then open com.fileserverapp.client package (located inside src/main/java folder) and select the FileReaderClient.java(execution should start after the server is started), run in eclipse, in such a way run various instances of the same program which would invoke multiple ServerConnection(threads are spun), now enter an operation(through command-line), prompt the name of the operation in a command line by typing the name for example, "index" would get response from the server in the form of total available files.
