Description

This Java application launches an HTTP server that processes requests to count the occurrences of a word in the text of "War and Peace". It's a multi-threaded server that can handle multiple requests simultaneously.

Features

  • HTTP server listening on port 8000.
  • Multi-threaded processing with a pool of 8 threads.
  • Word counting in the entire text of "War and Peace".
  • Input is provided via HTTP GET requests.

Requirements

  • Java Development Kit (JDK) must be installed to compile and run the application.
  • The text file "war_and_peace.txt" must be located in the ./resources/ directory relative to the application's executable.

Installation

  1. Clone the repository or download the source code.
  2. Ensure "war_and_peace.txt" is placed in the ./resources/ directory.
  3. Compile the code using a Java compiler. For example: 
    javac ThroughputHttpServer.java

Usage

  1. Start the server by running the compiled Java class. For example: 
    java ThroughputHttpServer
  2. The server will start listening for connections on http://localhost:8000.
  3. To count occurrences of a word in the text, make a GET request to http://localhost:8000/search?word=your_word_here. Replace your_word_here with the word you want to count.
  4. The server will respond with the count of the word's occurrences in the text.

Example

To count how many times the word "war" appears in the text, navigate to:

http://localhost:8000/search?word=war

The server will respond with the number representing the count of "war" in the text.

Code Structure

  • ThroughputHttpServer.java: The main server class that sets up the HTTP server and handlers.
  • WordCountHandler: An inner class implementing HttpHandler to process word count requests.

API Reference

The server accepts a single query parameter word which is the word to be counted in the text.

  • URL: /search
  • Method: GET
  • URL Params: word=[string]

Response Example

For a request to http://localhost:8000/search?word=peace, the server might respond with:

1024

indicating that the word "peace" appears 1024 times in the text.

Troubleshooting

If the server doesn't start, ensure that port 8000 is free and not being used by another service.
