intellij-idea Inspections
Introduction
Intellij IDEA provides lots of code inspections, that can significantly simplify writing code.
Inspections parameters can be found in Preferences | Editor | Inspections section. By default, IDEA has lots of them enabled. And lots of inspections support auto-fixing options, that can be seen on pressing Alt + Enter.
To run inspections for your whole project (or some custom scope), you need to select Analyze | Inspect code.
