IntelliJ IDEA is a powerful Java integrated development environment (IDE) for developing computer software for Windows PC. Every aspect of IntelliJ IDEA is specifically designed to maximize developer productivity. Together, powerful static code analysis and ergonomic design make development not only productive but also an enjoyable experience.
IntelliJ IDEA is a reliable software solution focused on developers’ productivity and efficiency. It provides you with a comprehensive set of tools and integrations with the most modern technologies and frameworks including Java, Scala, Groovy or other programming languages.
Since it is developed as a straightforward Java IDE, IntelliJ IDEA does provide support for web, enterprise and mobile frameworks and code assistance for all supported languages and frameworks.
Irrespective of which programming language you choose to develop mobile applications with, be it .NET, C++ or C#, IntelliJ IDEA comes with useful tools including UML Designer, SQL Editor or Bug Tracker Integration that make the development more productive.
The main window is user-friendly and displays by default the navigation toolbar and the ‘Project View’ section that allows you to view all the available files. Since the application does not include other perspectives like other IDEs do (for example Eclipse), you don’t need to switch between different workspace layouts to perform various tasks. It brings up the corresponding tools automatically and the actions stay the same all the time.
The Project section that can be accessed from the left panel of the application displays all the available components and libraries that help you develop various apps. However, since some files are generated automatically such as modules.xml or compiler.xml, you must be aware that by deleting them, the application won’t be able to run your scripts properly.
Additionally to Code completion, IntelliJ IDEA provides Smart Completion as well. While the first option helps you to complete the names of classes and variables, the latter option suggests only those types that are expected in the current context.
After writing your scripts, you can navigate to the ‘Code’ menu and perform various changes such as optimizing imports, implementing several methods and overriding them. Then, you are able to analyze dependencies by selecting the analysis scope.
To wrap it up, IntelliJ IDEA is a steady and practical solution worth having when you need to develop mobile and web platforms using intuitive editors for various programming languages such as LESS, TypeScript or CoffeeScript.
IntelliJ IDEA Features
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.
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 declaration. Press Ctrl+Shift+Space twice to get module.getProject() without any additional effort.
Static members completion
Lets you easily use static methods or constants. It offers a list of symbols matching your input and automatically adds required import statements.
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.
Knowing everything about 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.
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.
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.
Most of your time the editor (and the code) is the only thing visible on your screen, and you don’t need to leave it to do something that isn’t coding-related.
Quick popups are helpful for checking additional information without leaving the context that you’re in. When you press Ctrl+Shift+I shows you the definition for the symbol at caret.
To generate code, you don’t have to walk through complex wizards or fill huge forms.
Shortcuts for everything
In IDE Development software you have dedicated keyboard shortcuts for nearly everything, including rapid selection and switching between tool windows and the editor.
Accessing a tool window via its shortcut moves the input focus to it, so you can use all keyboard commands in its context. When you need to go back to the editor, just hit Esc.
When you’re in the Project tool window, you can not only navigate through the existing items but also create new ones by just pressing Alt+Ins.
Ergonomic user interface
All lists, trees, and popups in IDE Development software provide you with a quick search that instantly takes you to a set of items that contain the text you’re typing in them.
The first call of any IDE action is supposed to provide the most expected results. Need more results to Press the shortcut again and the IDE will go deeper to find what you need.
When you debug your code IDE Development software shows you variable values right in the source code, next to their usages.
You don’t even have to hover the mouse over the variable or switch to the Variables pane of the Debug tool window.
Any time a variable changes its value, the IDE highlights it with a different color so that you can better understand how the state is changed over the code.
IDE Development software allocates 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.
IDE Development software 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
Test runner and coverage
IDE Development software 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.
IDE Development software 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.
The IDE comes with a built-in terminal. Depending on your platform, you can work with the command line prompt, Far, Powershell, or bash. Invoke the terminal with Alt+F12 and execute any command–without leaving the IDE.
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.
IDE Development software 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.
Via a separate plugin, IDE Development software allocates a dedicated tool window that lets you connect to locally running Docker machines to manage images, containers, and Docker Compose services.
First-class support for top frameworks
IDE Development software allocates support for the most popular server-side and front-end frameworks.
Take advantage of extended coding assistance for Spring, Java EE, Grails, Play, Android, GWT, Vaadin, Thymeleaf, React, AngularJS and other frameworks.
Many languages–one IDE
IDE Development software is a turnkey solution, but if you ever need anything extra, its rich plugin ecosystem is here to help you.
IntelliJ IDEA Benefits
After IDE Development software has indexed your source code, it offers a blazing fast and intelligent experience by giving relevant suggestions in every context: instant and clever code completion, on-the-fly code analysis and reliable refactoring tools.
Mission-critical tools such as integrated version control systems and a wide variety of supported languages and frameworks are all to hand — no plugin hassle included.
Smart code completion
While the basic completion suggests names of classes, methods, fields, and keywords within the visibility scope, the smart completion suggests only those types that are expected in the current context.
The IDE predicts your needs and automates the tedious and repetitive development tasks, so you can stay focused on the big picture.
In every design and implementation decision that we make, we keep in mind the risk of interrupting the developer’s flow and do our best to eliminate or minimize it.
The IDE follows your context and brings up the corresponding tools automatically.
The coding assistance in IDE Development software is not about only the editor: it helps you stay productive when dealing with other aspects as well: e.g. filling a field, searching over a list of elements; accessing a tool window; or toggling a setting, etc.
