Code snippets can be helpful. Otherwise the can lead to code duplicates – so use them with wisely.

In JetBrains IntelliJ the code snipptes are called Live Templates. They are stored in files saved in C:\Users\{UserName}\.IntelliJIdea{Version}\config\templates on Windows and ~/.IntelliJIdea{Version}/config/templates on Linux.

In the Settings dialog you can use the search text box to quickly access the Live Templates section.

The Edit variables button switches to enabled state as soon as you user a variable name in the code.
