Have you worked with RabbitMQ?

Yes, I have worked with RabbitMQ in Java projects. RabbitMQ is a message broker that enables applications to exchange messages asynchronously and reliably.

Key points of working with RabbitMQ in Java:

• Using the amqp-client library for connection and interaction.
• Creating a connection and a channel.
• Declaring queues and exchanges.
• Sending and receiving messages.
• Handling acknowledgments for reliable delivery.

Example of sending a message to a queue in Java:

import com.rabbitmq.client.Channel;
import com.rabbitmq.client.Connection;
import com.rabbitmq.client.ConnectionFactory;

public class Send {
    private final static String QUEUE_NAME = "hello";

    public static void main(String[] argv) throws Exception {
        ConnectionFactory factory = new ConnectionFactory();
        factory.setHost("localhost");
        try (Connection connection = factory.newConnection();
             Channel channel = connection.createChannel()) {
            channel.queueDeclare(QUEUE_NAME, false, false, false, null);
            String message = "Hello RabbitMQ!";
            channel.basicPublish("", QUEUE_NAME, null, message.getBytes());
            System.out.println(" [x] Sent '" + message + "'");
        }
    }
}

Working with RabbitMQ allows building scalable and fault-tolerant systems with distributed task processing.
