This project is a real-time stock price ticker implemented using Core Java and Apache Kafka. The system reads stock price data from a data provider and publishes the data to a Kafka topic. The data can be consumed by a Java application that displays the prices in real-time using a user interface library such as Swing or JavaFX.

To run the project, you'll need to follow these steps:

• Download and install Apache Kafka from the official website.
• Start the ZooKeeper server using the command bin/zookeeper-server-start.sh config/zookeeper.properties.
• Start the Kafka broker using the command bin/kafka-server-start.sh config/server.properties.
• Create a Kafka topic named "stock-prices" using the command bin/kafka-topics.sh --create --topic stock-prices --bootstrap-server localhost:9092.
• Choose a data provider that provides real-time stock price data via a REST API.
• Write a Java application that connects to the data provider's REST API and retrieves the stock price data.
• Parse the response and extract the relevant data such as the symbol, price, and timestamp.
• Use the Kafka Java client API to publish the data to the "stock-prices" topic.
• Write a Java application that listens to the "stock-prices" topic using the Kafka Java client API.
• Parse the message payload and extract the relevant data such as the symbol, price, and timestamp.
• Update the user interface with the latest stock price data.
• Use a user interface library such as Swing or JavaFX to create a ticker display that scrolls through the latest stock prices in real-time.
• Add error handling and logging to the application.

• Java Runtime Environment (JRE) 8 or later
• ZooKeeper

To use the project, you'll need to:

• Start the data provider application and make sure it successfully publishes stock price data to the "stock-prices" topic.
• Start the ticker application and make sure it successfully consumes and displays the stock price data in real-time.
• Test error handling and make sure any errors are logged appropriately.
