How to add parameter label in IntelliJ?

Question

I just started using IntelliJ and while creating my first class and method I noticed something. When I wrote GomokuClient(4000); to call on a class from a imported library I of course got a error for the code not being complete, so I pressed the little red bulb to see the issue, and I selected the recommended fix. The fix looked like this:

Now I'm wondering, how do I write the portNumber:label in the parameter myself for other methods. Looked really nice and very helpful, and I'd like to know how to do this myself.

thanks beforehand!
