Why grayed var:colon is added in Java editor in IntelliJ

Question

I installed IntelliJ 2016.3.2 Build #IC-163.10154.41 Built on Dec.21, 2016

grayed var:colon is automatically added in front of argument in a caller method in Java e

Answer 1

The grey names followed by the colon are the parameter names from the method definition.

If you don't want them, right click on a grey word and select Disable Parameter Name Hints.

It's not a bug, it's a feature ;-)

If you want to reactivate it, go to Settings --> Editor --> General --> Appearance --> Option Show parameter name hints
