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!

The fix done by the IDE was not about setting parameter label, but instead adding the new() for ensuring the constructor call.

What you additionally see there is a feature of IntelliJ to show method's parameter hints/labels for easy understanding (readability) of the code. You can read more about parameter hints here: https://www.jetbrains.com/help/webstorm/viewing-method-parameter-information.html.
