Smart Code Completion

It is a set of techniques used to analyse the pieces of code to the developer. It supports context-based completion. It can detect and differentiate between big quantity of languages such as Java, JavaScript, Scala, SQL etc.

On-The-Fly Code Analysis

It helps to improve our code by identifying that an expression is valid or not and gives the compilation error if any. This feature will always analyse our source code regularly in the background which identifies the errors and provides possible improvements.

Refactoring process is a modification to the file. IntelliJ IDEA has a big range of refactoring option. It helps the developers to refactor his code faster and in a more secure manner. IntelliJ IDEA automatically suggests the refactoring. If it doesn't propose any refactoring option then we can select it from the refactor menu.
