Intellij code completion showing method / constructor parameter types and variable names

Question

I find it extremely annoying that you often don’t get help in defining method and constructor parameter signatures when you already wrote the first parameter.

Instead, Intellij will show the variables available to you in your context. This is good, but not the first prio. I want to see the signature of the method / constructor.

This means that you always need to delete and CTRL + SPACE to see the signature.

Is there any way to solve this problem?

Answer 1

You can press Ctrl + P to show the signature of the method / constructor, see this link for more details:

Answer 2

In fact, you do not need to press Ctrl + P , you can customize the idea to display information when you need it. Just select the Show full signatures and Autopopup in (ms:) fields, and the information will magically appear when you need it most, if you do not have to bend one finger.
