productive Java

Every aspect of IntelliJ IDEA has been designed to maximize developer productivity.

Together, intelligent coding assistance and ergonomic design make development not only productive but also enjoyable.

Deep intelligence

After IntelliJ IDEA 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.

Out-of-the-box experience

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.

Framework-specific assistance

While IntelliJ IDEA is an IDE for Java, it also understands and provides intelligent coding assistance for a large variety of other languages such as SQL, JPQL, HTML, JavaScript, etc., even if the language expression is injected into a String literal in your Java code.

Productivity boosters

The IDE predicts your needs and automates the tedious and repetitive development tasks, so you can stay focused on the big picture.

Developer ergonomics

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.

Unobtrusive intelligence

The coding assistance in IntelliJ IDEA 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.
