+# Distributed Locking with Apache ZooKeeper
+
+This project demonstrates a simple implementation of distributed locking using Apache ZooKeeper. The `Locks` class provides a mechanism to acquire and release locks in a distributed environment.

+## Overview
+
+Distributed locking is a critical mechanism in distributed systems to ensure that only one process can access a resource at a time. This project uses Apache ZooKeeper, a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services.
+
+## Prerequisites
+
+- Java 17
+- Apache Maven
+- Apache ZooKeeper (running on `172.29.3.101:2181`)
+

+- **Locks.java**: The main class that implements the distributed locking mechanism.
+- **pom.xml**: Maven configuration file that includes the necessary dependencies.
+
+## How It Works
+
+### Locks.java
+
+The `Locks` class implements the distributed locking mechanism using ZooKeeper. Here's a breakdown of the key methods:
+
+- **connectToZookeeper()**: Connects to the ZooKeeper instance.
+- **CheckLock()**: Checks if the `/locks` node exists in ZooKeeper. If not, it creates the node. It then creates an ephemeral sequential node under `/locks`.
+- **getLockOrWait()**: Attempts to acquire the lock. If the current node is the smallest in the sequence, it acquires the lock. Otherwise, it waits for the predecessor node to be deleted.
+- **run()**: Keeps the ZooKeeper connection alive by waiting on the ZooKeeper instance.
+- **close()**: Closes the ZooKeeper connection.
+- **process(WatchedEvent watchedEvent)**: Handles events from ZooKeeper, such as node deletion, to retry acquiring the lock.
+
+### Main Execution Flow
+
+1. **Connection**: The `main` method initializes the `Locks` instance and connects to ZooKeeper.
+2. **Lock Acquisition**: The `CheckLock` method is called to create the necessary nodes. The `getLockOrWait` method is then called to attempt to acquire the lock.
+3. **Lock Holding**: If the lock is acquired, the program holds the lock for 10 seconds and then releases it.
+4. **Lock Waiting**: If the lock is not acquired, the program waits for the predecessor node to be deleted.
+5. **Cleanup**: The ZooKeeper connection is closed.
+
+## Usage
+
+To use this distributed locking mechanism in your project, follow these steps:
+
+1. **Clone the Repository**:
+   ```bash
+   git clone <repository-url>
+   cd <repository-directory>
+   ```
+
+2. **Build the Project**:
+   ```bash
+   mvn clean install
+   ```
+
+3. **Run the Application**:
+   ```bash
+   java -cp target/DLock-1.0-SNAPSHOT.jar org.ds.Locks
+   ```
+
+## Dependencies
+
+The project uses the following dependency:
+
+- **Apache ZooKeeper**: Version 3.9.1
+
+The dependency is managed via Maven and specified in the `pom.xml` file.
+
+## Running the Project
+
+Ensure that ZooKeeper is running on `172.29.3.101:2181`. You can start the ZooKeeper server using the following command:
+
+```bash
+zkServer.sh start
+```
+
+Then, run the `Locks` class as described in the [Usage](#usage) section.
