How to enable Eclipse tooltips?

Question

Java

Tell me how to enable hints for work in Eclipse?

I watched a lot of videos on YouTube, there in eclipse
- Method calls in the code are indicated as links, you can conveniently click on them and go to the methods themselves
- Instant tips with errors in the code, etc.
- Instant check, for example, if the class has private fields, then when I try to write to them directly, an error

pops up in Eclipse when I hover over a part of the code, only it is empty)
More precisely, it is written - press F2 to focus.

Need a plugin?
