Apache Kafka is a popular distributed streaming platform used by many organizations to handle large volumes of data in real-time. One of the key components of Kafka is the ability to create and manage topics. In this article, we will provide a step-by-step guide on how to create Kafka topics using the Java API in an IDE.


Before we dive into creating Kafka topics with Java API, make sure you have the following prerequisites:

  • Java Development Kit (JDK) installed on your system
  • An Integrated Development Environment (IDE) such as Eclipse or IntelliJ IDEA
  • Kafka installed and running on your system

Step-by-Step Guide

Follow these steps to create Kafka topics using the Java API in an IDE:

Step 1: Import Kafka Libraries

The first step is to import the Kafka libraries into your project. You can do this by adding the following dependencies to your pom.xml file if you are using Maven:


If you are using Gradle, add the following to your build.gradle file:

implementation 'org.apache.kafka:kafka-clients:2.8.0'

Step 2: Create Kafka Topic

Next, create a Kafka topic by using the following code:

import org.apache.kafka.clients.admin.AdminClient;
import org.apache.kafka.clients.admin.AdminClientConfig;
import org.apache.kafka.clients.admin.NewTopic;
import java.util.Collections;
import java.util.Properties;

public class KafkaTopicCreator {
    public static void main(String[] args) {
        // Set up client configuration
        Properties properties = new Properties();
        properties.put(AdminClientConfig.BOOTSTRAP_SERVERS_CONFIG, "localhost:9092");
        AdminClient adminClient = AdminClient.create(properties);

        // Create topic
        NewTopic newTopic = new NewTopic("test-topic", Collections.emptyMap());

This code creates a new Kafka topic named "test-topic" with default configurations. You can change the topic name and configurations as per your requirements.

Step 3: Run the Code

Finally, run the code to create the Kafka topic. You can do this by right-clicking on the file and selecting "Run As" > "Java Application" in Eclipse. In IntelliJ IDEA, you can right-click on the file and select "Run KafkaTopicCreator.main()" from the context menu.


Creating Kafka topics using the Java API in an IDE is a simple and straightforward process. By following the steps outlined in this article, you can create Kafka topics and manage them efficiently. Remember to import the Kafka libraries into your project, create the topic using the Java API, and run the code to create the topic. Happy coding!
