How to turn off type hint in java stream sequences

Question

When I have code in java that uses streams intellij displays type hints about the result of the stream.

I would like to disable these hints

Example with the following code:

Stream.of (1, 2. 3)
    .map (n -> n + 1)
    .map (n -> n % 2 == 0 ? "even number " + n : "odd number " + n)
    .peek (System.out:println)
    .map (s -> Float.parseFloat (s.substring (s.lastIndexOf (" "))))
    ;

I have turned off other tool tips for parameters, but the hints after the streams are still present. They are visually very distracting while providing me with little extra information.

I would also be happy if I knew how to change the color or style of the hints (I have Material Theme UI installed)

1. Navigate to: Preferences -> Editor -> Inlay Hints -> Java. Alternatively, press CMD (⌘)/Ctrl + Shift + A, search for Inlay Hints, open the first result, and select Java.
2. Untick Method Chains tickbox

Alternatively, you can increase the count of unique types in streams/method chains from which the type hints will be shown. I.e., if your stream transforms from type A to type B, and then to type C, this would be 3 types. If you set it to 2, hints would be shown for 3 unique types and more.

An easier way!

Just right click on where it says (in your example) Stream<Integer> and untick the option Show method chain hints

Alternatively, hit CTRL+ALT+A and type "show me" - you can see the setting for "Show method chain hints"
