Books and resources on OOP?

Question

Java

At one time there was a problem with solving problems (like on codewars etc), but I thought everything was ok with OOP. Now I am going through the stages of social security and I understand that the PLO is a mess in my head: I get lost and confused on seemingly simple questions. Please share resources and experience in order to know the three whales or how many there are.
The crux of the matter: material is needed, both practical and theoretical. Practical - examples that are clearly written (as with the use of Solid, patterns (optional, but desirable ^ and just ordinary ones).
Theoretical - I would like to see examples with code and UML, read why this way or that. (I found a book on c# "Beginning c# object-oriented programming" by Daniel Clark - flipped through, but haven't read it yet - PS did someone read it? how do you like it?).
It doesn't matter in English or Russian, in java or c#.
I would be very grateful.
