IntelliJ IDEA For Java 2020.3.2

IntelliJ IDEA is an integration software by JetBrains which provides solutions for different languages in one pack. The free IDE is easy to use and is only centered on productivity and the free flow of work.

Being a developer it is sometimes hard to use more than two languages at a time in a single project so, the core function of this software is to promote developer productivity. The Java IDE’s Intelligent coding assistance and ergonomic design make development quite fun with the flow when you are working on a complex programming project.

The IntelliJ software lets you work on most useful languages like Java, Python, Clojure, Kotlin, R. The software works on plugin system so when you need to start coding in Python other than Java, you’ll need to install the Python plugin and then you can migrate from one language to another. The software provides a user-friendly window that has a navigation toolbar with a project view section that shows the available files. The best function provided by IntelliJ IDEA is Code Completion due to which, when you write a code incomplete; it suggests the complete code and auto-fills, which saves your time like auto typing in android keyboards does. As spoken of Android, App development is made easy by UML Designer, SQL Editor, and Bug Tracker integration, and many more.

The software has integrated with multiple servers like Tomcat, GlassFish, JBoss, Weblogic, Websphere for debugging purposes.

The Default languages in this integrated development environment software are Java and almost free, Kotlin, Groovy, and XML/XSL.

The free languages of IntelliJ Community Edition that require plugins are

Clozure	CloudSlang	Dart
Elm	Erlang	Gosu
Haskel	Haxe	Julia
Lua	Perl	Python
Rust	Scala	R

 

While IntelliJ Ultimate Edition gives you access to other helpful languages like

ActionScript/MXML	CoffeeScript	Go (via a plugin)
HTML/XHTML/CSS	JavaScript	PHP (via a plugin)
Ruby/JRuby	SQL	TypeScript

IntelliJ IDEA Features:

1) Smart completion

Ctrl+Shift+Space gives you a list of the most relevant symbols applicable in the current context. This and other completions are constantly learning from you, moving the members of the most frequently used classes and packages to the top of the suggestions list, so you can select them faster.

2) Chain completion

Digs a tad deeper than Smart Completion and lists applicable symbols accessible via methods or getters in the current context. Say you’re looking for a value of Project and only have the Module module declaration. Press Ctrl+Shift+Space twice to get module.getProject() without any additional effort.

3) Static member completion

Lets you easily use static methods or constants. Offers a list of symbols matching your input and automatically adds required import statements

4) Data flow analysis

When offering completion variants, IntelliJ IDEA analyses data flow to guess the possible runtime symbol type and refines choices based on that intel, automatically adding class casts.

5) Language Injection

Brings coding assistance for a selected language to expressions and string literals in another one, complete with all advantages you would normally have. For example, you can inject fragments of SQL, XPath, HTML, CSS, or JavaScript code into Java String literals.

6) Cross-language refractories

Knowing everything about the usages of a symbol, IntelliJ IDEA offers extremely effective, thorough refactorings. For example, when you Rename a class within a JPA statement, it will update everything, from the JPA entity class to every JPA expression where it is used

7) Detecting Duplicates

Finds duplicate code fragments on the fly. Even if you’re only about to extract a variable, constant, or a method, IntelliJ IDEA will let you know that there is a similar code fragment that can be replaced along with the one you’re working on

8) Inspections and quick fixes

Whenever IntelliJ IDEA detects that you’re about to make a mistake, a little lightbulb pops up in the editor. Clicking it or pressing Alt+Enter opens a list of actions you can take to make things right.

IntelliJ IDEA’s Built-in Developer Tools

To streamline your workflow, IntelliJ IDEA offers an unbeatable toolset right from the first start: decompiler, bytecode viewer, FTP, and many more.

1) Version control

IntelliJ IDEA provides a unified interface for major version control systems including Git, SVN, Mercurial, CVS, Perforce, and TFS. The IDE lets you browse the history of changes, manage branches, merge conflicts, and much more

2) Build tools

IntelliJ IDEA supports Maven, Gradle, Ant, Gant, SBT, NPM, Webpack, Grunt, Gulp, and other build tools. Seamlessly integrated, these tools help automate compilation, packaging, running tests, deployment, and other activities

3) Test runner and coverage

IntelliJ IDEA lets you perform unit testing with ease. The IDE includes test runners and coverage tools for major test frameworks, including JUnit, TestNG, Spock; Cucumber, ScalaTest, spec2, and Karma.

4) Decompiler

IntelliJ IDEA comes with a built-in decompiler for Java classes. When you want to take a look inside a library that you don’t have the source code for, now you can – without any third-party plugins.

5) Terminal

The IDE comes with a built-in terminal. Depending on your platform, you can work with command line prompt, Far, Powershell, or bash. Invoke the terminal with Alt+F12 and execute any command–without leaving the IDE.

6) Database tools

Take advantage of intelligent coding assistance when editing SQL; connect to live databases; run queries; browse and export data; and even manage your schemes in a visual interface–right from the IDE.

7) Application servers

IntelliJ IDEA supports major application servers: Tomcat, JBoss, WebSphere, WebLogic, Glassfish, and many others. You can deploy your artifacts onto application servers and debug the deployed applications right from within the IDE.

8) Docker

Via a separate plugin, IntelliJ IDEA provides a dedicated tool window that lets you connect to locally running Docker machines to manage images, containers, and Docker Compose services.

Conclusion

Finally, apart from its competitors like Eclipse and Visual Studio, IntelliJ provides Code Completion which offers little suggestions for variables, types, methods, and expressions, and hence functions like these make this software more favorable for passionate Java developers for Android and Web platforms.

The Overpriced IntelliJ Ultimate Edition might make your pocket burn but we assure you the software will not let you down when it comes to development in Python and other well-known languages like PHP and SQL.
