Java Process Pipeline

Java implementation of an operating system process pipeline

Overview

This project provides a practical implementation of an operating system process pipeline using Java, designed to illustrate concepts such as inter-process communication and stream handling.

The project comprises three main components:

• Generator: a utility for generating random text strings.
• Analyzer: a utility for analyzing text input.
• Launcher: an orchestrator for the execution of the pipeline.

To get the pipeline launched using Java, Launcher starts a new Generator process and pipes its output directly to an Analyzer process, as described in the following diagram:

Alternatively, the pipeline can be launched manually by connecting the output of Generator to the input of Analyzer using the pipe operator (|).

See Usage for more information.

NOTE: Due to its educational nature, this project is not intended to represent a production-ready solution. It is a demonstration of various design patterns, advanced features, and coding techniques. While the code may illustrate good programming practices, it may not adhere to all the best practices necessary for a real-world, production-grade application.

Requirements

Java 11 or newer

Usage

Launch the pipeline with Launcher

Compile Generator, Analyzer and Launcher classes:

javac src/Generator.java
javac src/Analyzer.java
javac src/Launcher.java

Launch the pipeline running Launcher:

java -cp src Launcher

Launch the pipeline manually

Compile Generator and Analyzer classes:

javac src/Generator.java
javac src/Analyzer.java

Launch the pipeline using the pipe operator (|):

java -cp src Generator 2 | java -cp src Analyzer
