Android Studio comment shortcut

For code formatting in Android Studio: Ctrl + Alt + L (Windows/Linux) Option + Cmd + L (Mac) 16 May 2013

To reformat your code manually, press Ctrl + Alt + L (or using the menu Code | Reformat code… ). To reformat the whole source code of your module, just select the module folder first. In ‘File | Settings | Code Style | Java’ there is only 2 options- Default and Project. I need to create a new style other than that.

java.text.Format. Known direct subclasses. DateFormat, MessageFormat, NumberFormat, SelectFormat, UFormat. DateFormat. DateFormat is an abstract class for date/time formatting subclasses which formats and parses dates or time in a language-independent manner.
