IntelliJ IDEA 2018.2 Help

Intention actions

As you work in the editor, IntelliJ IDEA analyzes your code, searches for ways to optimize it, and detects potential and actual problems.

As soon as the IDE finds a way to alter your code, it displays a yellow bulb icon yellow bulb icon in the editor next to the cursor. By clicking this icon, you can view intention actions available for this unit of code. Intention actions cover a wide range of situations from warnings to optimization suggestions. You can open the full list of actions, view their descriptions, and disable intentions in the settings.
