How can IntelliJ show type hints for automatically inferred local variables in Java 10?

Question

IntelliJ shows type hints for local variables in Kotlin as shown here:

This makes it easy to see the type of variables even if their types are inferred. Java 10 introduces type inference for Java with the var keyword. However, IntelliJ does not show any type hints by default:

After searching the internet for a bit, I was unable to find any information on how to enable type hints for local variables for Java. Is this even possible currently?

I use IntelliJ Community Edition 2019.1 on Windows 10.

It's already supported, see youtrack.jetbrains.com/issue/IDEA-194935 . – Desmid

Not quite the same feature -- what they have implemented is showing the hints when you fold the var declaration line. – Chary

Answer 1

Turn on option at:

Preferences > Editor > Inlay Hints > Types > Java > Implicit types.

You might also consider turn on all the options at:

Preferences > Editor > Inlay Hints > Parameter names > Java.

In the latest version of IntelliJ (2020.3) these are called "Inlay Hints"

The closest feature in Java is Replace 'var' with inferred type:

Settings -> Editor -> General -> Code Folding -> Replace 'var' with inferred type
