In Eclipse, when I enter code Thread.sleep(100), the code will be wrappered by try catch after entering keys: ctrl+1 and enter. In Android studio what can I do for wrapper it by try catch easily? Is there a shortcut?

To open the keymap settings, choose File > Settings (on Mac, Android Studio > Preferences) and navigate to the Keymap pane. Figure 1. The Android Studio keymap settings window. Keymaps dropdown: Select the desired keymap from this menu to switch between preset keymaps.
In Eclipse, just surround the code you want to enclose with the try-catch block and right-click, then select **Surround with > Try Catch **block. Although you can only have one try statement per try-catch block, you can have multiple catch blocks.
Try/catch is used when an Exception can be thrown from the code, and you catch it in the catch-clause, which is an object oriented way to handle errors. You can't catch Exceptions with if/else blocks - they share nothing with try/catch.
Highlight the code you want to surround with try/catch
For Windows it is:
Press Ctrl + Alt + t
For Mac it is:
Press cmd + Alt + t
Select the item you want (#7 for try / catch)
There is no need to "type" try first however, highlighting your code works better.
