Is there a simple JAVA class editor with syntax checking, autocomplete?

Question

Java

Hello.
A JAVA class for working with bluetooth got into the Unity project (it is assembled in a JAR separately).
It is necessary to somehow check the syntax at the stage of writing, to catch the simplest errors when building or running on Android, much time is wasted.
I'm looking for something small and fast.
For Windows.
Thank you all for your help!

Answer 1

Atom or VS Code

Answer 2

VS code.
A little harder (if you do not use all the features and turn off unnecessary panels) will be IDEA. At the same time, it is the most functional IDE.
