Operating Systems Concepts in Java

Welcome to the Operating Systems Concepts in Java repository! This project provides implementations of fundamental operating system concepts in Java. It serves as an educational resource for students, developers, and enthusiasts looking to understand key OS algorithms and mechanisms through practical code examples.

Overview

This repository contains Java implementations of various operating system concepts, including process scheduling, memory management, and synchronization techniques. Each concept is implemented in a separate Java file, designed to be clear, modular, and easy to understand. The code is ideal for learning purposes or as a reference for building more complex systems.

Implemented Concepts

The following operating system concepts are included in this repository:

• Process Scheduling Algorithms:
  • Round-Robin Scheduling
  • First-Come, First-Served (FCFS)
  • Shortest Job First (SJF)
  • Priority Scheduling
• Memory Management:
  • Page Replacement Algorithms (e.g., FIFO, LRU)
  • Memory Allocation Strategies
• Synchronization:
  • Semaphores
  • Monitors
  • Producer-Consumer Problem
• Deadlock Handling:
  • Banker's Algorithm
  • Deadlock Detection
• File Systems (if applicable):
  • Basic file system operations or simulations

Each implementation is located in the src/ directory, with individual Java files for each concept.

Getting Started

Prerequisites

• Java Development Kit (JDK): Version 8 or higher.
• A Java IDE (e.g., IntelliJ IDEA, Eclipse) or a text editor with a Java compiler.

Installation

1. Clone the repository:

   git clone https://github.com/sercankulcu/operating-systems-java.git

2. Navigate to the project directory:

   cd operating-systems-java

3. Compile the desired Java file(s) using a Java compiler or IDE:

   javac src/<Concept>.java

   Note: Most files are standalone implementations without a main method. You may need to create a test class to run or test the code.

Usage

Each operating system concept is implemented as a Java class or set of methods. To use an implementation:

1. Import the desired class into your Java project.
2. Create an instance or call the methods to simulate the OS concept. For example:

   RoundRobin scheduler = new RoundRobin();
   scheduler.addProcess(new Process(1, 10)); // Process ID, burst time
   scheduler.run();

3. Refer to the source code in src/ for detailed method signatures and implementation details.

Contributing

Contributions are welcome! If you'd like to add new OS concepts, improve existing implementations, or fix bugs, please follow these steps:

1. Fork the repository.
2. Create a new branch (git checkout -b feature/your-feature).
3. Commit your changes (git commit -m "Add your feature").
4. Push to the branch (git push origin feature/your-feature).
5. Open a pull request.

Please ensure your code adheres to Java coding conventions and includes clear comments or documentation.
