Sharing is caring!

Java developers use this technology to create different types of applications (banking apps, standalone apps – Microsoft Office, client server apps – Yahoo chat, web apps – Facebook). In order to create a java app, developers can’t do the job without the right tools which will help them to improve the quality of their code. Be one of the nine million developers who chose to create applications using this popular programming language that was founded in 1995 and prepare for a future career in this field. For starters, you’ll need some tools necessary to compile, debug, and run your application and in this article, we’ll give you some recommendations.

jconsole

This graphical monitoring tool is used for monitoring Java Virtual Machine (JVM) and Java applications and it runs on local and remote machines. Also, it uses Java Management Extensions (JMX) technology to provide information on performance and resource consumption of apps created and running on this platform.

HeapAnalyzer

It will find possible Java heap leak area through the search engine and it will analyze the JavaTM heap dump in Java apps. It will create directional graphs and will transform them into directional trees, then it will execute the heuristic search engine.

JAMon



This app monitor is free and easy to use. It’s used to determine app performance bottlenecks, app scalability and user/application interactions. In addition, it gathers summary statistics (execution times, hits and simultaneous application requests).

Guava

Google’s engineers have launched this open-source set of common libraries for Java, at the beginning of December 2015. It has three components: an extension to the Java collections framework, basic utilities – which are used to reduce menial labors and to implement common methods and behaviors and lastly, while other utilities are in charge with functional programming, caching, range objects and hashing.

VisualVM

With this tool you’ll view detailed information about Java apps while they’re running on a JVM. Data from Java virtual machines is organized by the Java Development Kit (JDK) tools and the information is presented in a way that allows data from multiple Java apps to be viewed without any problems.

Eclipse Memory Analyzer

You’ll need this Java heap analyzer rich in features to find memory leaks and to reduce memory consumption. AME is capable of calculating the retained sizes of objects and it’s able to detect what prevents the Garbage Collector from collecting objects.

YourKit

This Java profiler delivers innovative, smart and powerful analysis capabilities. Thanks to its unique on-demand profiling, the app will run with zero overhead and the actual profiling will be activated only when it’s necessary.

Guice

This open source software framework created by Google under the Apache License has been around for over a year. With this tool, you’ll get support for dependency injection, which is a design pattern that separated behavior from dependency resolution.

Eclipse

This is the best open-source integrated development environment (IDE) that any Java developer should use, as it provides a base workspace and an extensible plug-in system with which the environment will be customized.

Clover

Atlassian is the creator of this code coverage tool which runs in the IDE and generates code coverage reports from unit tests. If you’re also using Eclipse, or Maven, or Ant, Clover can be executed as a plugin.

Every techie needs a pair of sick headphones. Neurogadget recommends these Audio Technica Professional Studio Monitor Headphones for both their quality and their cool-factor.
