How to define a live template

Go to File->Settings->Editor->Live Templates.
In the right panel tree select category other.
Click the plus (+) sign on the top right, select Live Template.
Set
    Abbreviation: log
    Description: Inserts private static Logger for slf4j
    Template text: private static final org.slf4j.Logger logger = org.slf4j.LoggerFactory.getLogger($CLASS_NAME$.class);$END$
Now click the Edit Variables button, we will tell the IDE what $CLASS_NAME$ means here. $END$ means where to place the cursor after template expansion.
    Name: CLASS_NAME
    Expression: className()
    Default value: leave empty
    Skip if defined: true (check the checkbox)
At the very bottom look for text Applicable in with a link Change next to it, click it. Select Java->declaration.

Congratulations, you’re done! Just type log and press Tab anywhere in the class declaration.
