15 Best JAVA Tools for Development, Build, Profiler, Code Coverage and Review

15 Best JAVA Tools for Developers: Top Java Development Tools for Build, Profiling, Code Coverage and Code Review

Java is the most popular high-level object-oriented programming language that is widely used across the globe.

In 2010, Oracle Corporation bought SUN Microsystems and now Oracle is responsible for each and every change in java. Java has gained enormous popularity since it appeared.

Unlike other programming languages, Java programs are compiled independently of the platform. Java is a simple, object-oriented, distributed, interpreted, robust, secure, portable, multi-threaded and dynamic programming language.

Best JAVA Tools

This article is a combination of some interesting as well as simple java tools for developers and testers to help them to make their code easy to write, compile and debug.

These top java development tools are available as open-source and licensed too and have a free-trial version available in the market so that you can use and gain hands-on experience before deciding which tool would be useful in the context of your code.

Best JAVA Tools for Developers

Enlisted below are the most popular JAVA Development Tools that are popular in the market for Java Build, Profiling, Coverage, and Review.

We have also covered the list of the most popular Java Testing Frameworks and Tools here.

Let’s review each in detail.

#1) SonarQube


SonarQube has been empowering developers to write cleaner and safer code since 2008. It’s static analysis of Java includes over 600 unique rules to detect bugs, security vulnerabilities, security hotspots and code smells in your Java code for better reliability, security and maintainability.

SonarQube offers support through Java 16, as well as support for common ORMs and Java frameworks. SonarQube also offers rules for regular expression correctness and robustness that are unique in the industry. Integrations with Maven, Gradle and common CIs make analysis easy.

With broad OWASP Top 10 coverage for Java, SonarQube brings issues to developers early in the process to help you protect your systems, your data and your users. Push notifications and open APIs make integrating with your other systems painless.

Analysis is free and open source, with additional detection of injection flaws in Java available in SonarQube’s commercial editions.

When your SonarQube instance is paired with SonarLint (a free plugin for your IDE) in ‘Connected Mode’, you establish a continuous code quality analysis cycle that keeps your codebase clean from the moment you write your first lines of Java code.
