10 Useful Tools for Java Developers

Every Java development team has a set of tools to get through office challenges. Java programmers have an enormous selection of libraries, utilities, and programs at their disposal.

Today we have listed 10 must have tools for Java developers.

Keep in mind that these tools make life simpler for you, only if you know your way around Java.

1. JDK (Java Development Kit)

If you plan on developing Java based applets and applications, the first logical step is to get yourself a tool like JDK, which includes the necessary Java Complier, the Java Runtime Environment, and the Java APIs. This tool will help you get started with Java.

2. Eclipse

Eclipse is an open-source integrated development environment (IDE) for Java that facilitates the creation of mobile apps development, desktop and web applications. Eclipse is a highly versatile and adaptable tool that offers modern features and consists of a set of modelling tools, java testing tools and a development framework.

3. Gradle

If you want a tool that is a combination of everything that is good about the ANT and Maven, you will be very happy with this Gradle. The huge advantage of this tool is that it supports the convention-over-configuration paradigm. Gradle includes additional plugins for adding new languages, checking for updated dependencies generating project files for IDEs, building native binaries, and more.

4. JUnit

JUnit is an open source framework for writing and running unit tests. There is an essential difference between JUnit and other similar frameworks available. With JUnit you can test one block of code at a time rather than waiting for the module to be completed before you run a test.

5. Akka

Akka is a complete toolkit and a Java runtime for developing concurrent, distributed and message-driven applications on the Java Virtual Machine. Akka is widely used by popular companies, including Cisco, Amazon, BBC and Groupon. This tool offers features, such as adaptive cluster management, asynchronous design, load balancing, routing, abstractions in Java and much more.

6. Javadoc

Javadoc is a documentation generator provided by Oracle. This tool parses specially formatted comments into HTML documents.

7. Keytool

Keytool is part of JDK by Oracle. Even if is rarely used tool in the development environment, in some enterprise level applications, Keytool is the best key and certificate management tool.

8. Play

A powerful web framework for developing web applications in Scale and Java. Play its built on top of Akka and uses an asynchronous model. Play is real-time enabled and supports various third-party Java libraries.

9. Apache Log4j

Apache Log4j is a logging java library and it’s useful for detecting application failures. It has a unique feature called as inheritance in loggers, which helps reduce the volume of logged output and the cost of logging.

10. VisualVM

VisualVM is a utility for monitoring and reviewing the performance of Java applications that detects and attaches to active JVM instances to retrieve diagnostic information about a process.

With the help of VisualVM you can easy diagnose performance issues in real time. Also, this tool provides a full suite of profiling tools including JConsole, jstack, jmap, jinfo, and jstat.

These 10 tools cover the full gamut of Java development, from code building to bug squashing. Learning these tools can help you improve the quality of your code and become a more efficient Java developer.

The Java landscape is constantly changing with new tools, utilities, and libraries. This list is just a recommendation of tools you need to try out before you get to work.
