Concurrency and Multithreading in Java

This repository contains Java programs that demonstrate concepts of Concurrency and Multithreading, including inter-thread communication, synchronization, and common producer-consumer scenarios.

🔍 Descriptions

1. ProducerConsumerPrblm_ImplmtngBlockingQueue.java

A custom implementation of a Blocking Queue to solve the classic Producer-Consumer problem using:

• synchronized blocks
• wait() and notifyAll() for inter-thread communication
• Bounded queue behavior using a LinkedList with capacity limits

This file creates two threads:

• Producer (Thread1) adds integers to the queue.
• Consumer (Thread2) removes integers from the queue.

2. ThreadSleepInLoop.java

Demonstrates use of Thread.sleep() in a for loop to simulate thread execution delay and observe behavior over time.

✅ Concepts Demonstrated

• Java Thread Lifecycle
• Synchronization with intrinsic locks
• Inter-thread signaling using wait() and notifyAll()
• Queue operations in concurrent context
• Thread-safe design using intrinsic object monitor

🛠 How to Run

1. Clone the repository:

   git clone https://github.com/Awadhesh-Gupta/ConcurrencyNdMultithreading.git
   cd ConcurrencyNdMultithreading

2. Compile the code:

   ```bash
   javac src/multithreadingClass/*.java
   ```

3. Run the main class:

   ```bash
   java -cp src multithreadingClass.ProducerConsumerPrblm_ImplmtngBlockingQueue
   ```

## 📌 Requirements

* Java 8 or higher
* Basic understanding of threads and synchronization
