Best IDEs and Tools for Java Development: From A to Z

Java remains one of the most in-demand programming languages in the world, and choosing the right tools directly impacts development speed and code quality. In this article, we will review the best IDEs and auxiliary tools for a Java developer — from the initial stage to professional production.

1. Integrated Development Environments (IDEs) for Java

Modern Java development is practically unthinkable without a powerful IDE. Let's look at the three main market leaders.

IntelliJ IDEA

The undisputed leader among Java developers. IntelliJ IDEA from JetBrains is available in a free Community version and a paid Ultimate version (with support for Spring, Hibernate, Docker, and enterprise frameworks).

Smart autocomplete — predicts code even in complex generics.
Refactoring — safe renaming, method extraction, inlining.
Built-in debugger and profiler.
Integration with Git, Maven, Gradle, Docker, and databases.

// Example of autocomplete in IntelliJList<String> names = Arrays.asList("Anna", "Ivan", "Maria");names.stream()     .filter(n -> n.startsWith("A")) // IDEA will suggest the startsWith method     .forEach(System.out::println);

Eclipse

A classic open-source IDE. It is especially popular in large enterprise projects due to its flexible plugin system.

Free and cross-platform.
Powerful editor with support for JDT (Java Development Tools).
Extensive customization options via the Marketplace.
Excellent support for application servers (Tomcat, JBoss).

// Example of Quick Fix in Eclipsepublic class Main {    public static void main(String[] args) {        // Eclipse will highlight the error and suggest importing the class        // ArrayList list = new ArrayList(); // Ctrl+1 → "Add import"    }}

NetBeans

The official IDE from Apache, which is great for learning and rapid prototyping.

Support for Java SE, EE, and ME "out of the box".
Built-in GUI designer for Swing and JavaFX.
Simple project and build tool configuration.

2. Build Systems and Dependency Management

No serious project can do without build automation.

Maven

The de facto standard in the Java world. It uses XML configuration (pom.xml) and the centralized Maven Central repository.

<!-- Example pom.xml --><project>    <modelVersion>4.0.0</modelVersion>    <groupId>com.example</groupId>    <artifactId>my-app</artifactId>    <version>1.0-SNAPSHOT</version>    <dependencies>        <dependency>            <groupId>org.junit.jupiter</groupId>            <artifactId>junit-jupiter-api</artifactId>            <version>5.10.0</version>            <scope>test</scope>        </dependency>    </dependencies></project>

Gradle

A modern alternative to Maven, based on Groovy or Kotlin DSL. It is known for its high performance and flexibility.

// Example build.gradle (Groovy)plugins {    id 'java'}

repositories {    mavenCentral()}

dependencies {    testImplementation 'org.junit.jupiter:junit-jupiter:5.10.0'}

test {    useJUnitPlatform()}
