Overview of Java Tools

Java is an object-oriented programming language a developer uses to develop applications, websites, etc. It is a platform-independent language, i.e., it can run on any platform machine; there is no restriction. A portable feature of Java enables an application written in Java language to run on any platform. There are multiple Java Tools available that developers use to develop the application. Here in this article, we are going to discuss those tools.

List of Java Tools

Below are some of the tools of Java used by developers –

1. Java Development Kit

5. Eclipse

Eclipse is an integrated Java-free open-source development framework. Eclipse offers much-needed help to complete code, refactor and check syntax. It provides new features, many models of tools, java testing techniques, and frameworks for growth. It also provides a variety of tool plugins for developing various Java apps called the Java Development Tools Project (JDT).

6. Gradle

Gradle is a Java tool for project automation. It builds on Apache Ant and Apache Maven features.

Features of Gradle:

Better dependency modeling with the Java Library plugin decreases the volume of the classpath compilation.
Gradle Wrapper allows Gradle to be performed on computers that are not assembled.
Its intelligent classpath helps prevent the need to build when a library’s binary interface has not changed.

7. Java decompiler

Java Decompiler is a Java freeware tool reconstructing the CLASS Java source code. To make Java source code precise, you can decompile Java applets, JAR, and ZIP files. You can use a Java decompiler to view predefined Java class data such as HashMap, HashSet, ArrayList, etc.

Features of Java DeCompiler:

javaDeCompiler tools support drag-and-drop options.
In Java, decompiler source code shows the color coding,
It works for almost all versions of Java,

8. JUnit

JUnit is a testing tool used for Java programming. It is open-source; it is free.

Features of JUnit:

With the help of this tool, writing and running test scripts becomes easy
It is Used to load the database with a specific set of data.
It provides annotations to identify different types of test methods and test cases efficiently.
It allows faster coding so that the quality and speed of development increase.
It is used to Prepare other objects and sets of inputs.

9. Apache JMeter

The Apache JMeterTM ly open-source Java software, first created by the Apache Software Foundation’s Stefano Mazzocchi to load functional behavior testing and performance measurement. Originally, JMeter was used to test Web Applications or FTP. JMeter is currently used for functional testing, database server testing, etc.

Features of Apache JMeter:

JMeter allows different server types to perform load and performance testing.
This tool stores its test plans in XML format, allowing users to make the test plan using a text editor.
The tool is also used to test the apps automatically and functionally.
Plugins for data analysis and visualization allow extensibility and customization.
Functions should provide dynamic input for information manipulation testing.

10. Groovy

Groovy is a powerful object-oriented language for the Java platform. The primary goal of this Groovy is to increase the production speed of developers. It runs on JVM, i.e., Java Virtual Machine.

Features of Groovy:

It highlights syntax and errors automatically, like NetBeans, which helps avoid programming mistakes.
It can integrate with Java or any third-party libraries
