IntelliJ shortcut to insert null check?

Question

Is there a shortcut to insert code:

if (someParameter == null) throw NullPointerException("someParameter is null"); 

Answer 1

Try ifn and then Tab. You can find more of those or define your own by going to the settings and searching for "Live Templates".

Answer 2

IntelliJ IDEA provides other shortcut-like functionality that can help with your performance, namely Postfix completion .

If you want to insert a null check, enter ".null" after the variable name, for example

and zero code will be inserted automatically, for example

IntelliJ IDEA provides more convenient postfix replenishment, which you can find in the settings in Editor> General> Post-completion

Answer 3

There is no template for this, but you can easily create one. Just follow the instructions here .

Now there is an easy way to do this (in version 13.1), described here: http://blog.jetbrains.com/idea/2014/03/postfix-completion/

Answer 5

If everything is fine with the comments in the code, you can try the solution mentioned here . It does not solve the problem directly, but if you have such zero checks in many places, you can use this :)
