Deep insight into your code
IntelliJ IDEA analyzes your code, looking for connections between symbols across all project files and languages. Using this information it provides indepth coding assistance, quick navigation, clever error analysis, and, of course, refactorings.

• Smart completion
• Chain completion
• Static members completion
• Data flow analysis
• Language injection
• Cross-language refactorings
• Detecting duplicates
• Inspections and quick-fixes

Developer ergonomics
Every aspect of IntelliJ IDEA is designed with ergonomics in mind. IntelliJ IDEA is built on a principle that every minute a developer spends in the flow is a good minute, and things that break developers out of that flow are bad and should be avoided.

• Editor-centric environment
• Shortcuts for everything
• Ergonomic user interface
• Inline debugger

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.

• Version control
• Build tools
• Test runner and coverage
• Decompiler
• Terminal
• Database tools
• Application servers
• Docker

Polyglot experience
In addition to Java, IntelliJ IDEA offers first-class support for top JVM and non-JVM frameworks and languages out of the box.

• First-class support for top frameworks
• Many languages–one IDE

You do not need to install Java to run IntelliJ IDEA, because JetBrains Runtime is bundled with the IDE (based on JRE 11). However, to develop Java applications, a standalone JDK is required.
