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 current line. By clicking this icon, you can view intention actions available in the current context. Intention actions cover a wide range of situations from warnings to optimization suggestions. You can view the full list of intentions and customize them in the Settings dialog Ctrl+Alt+S.
