How to start learning Java with some programming background?

[pkrzysiek]

Hello,I want to start learning Java in order to read some algorithm and clean code books and maybe getting deeper later with it as a backend language.My question is that,what are the sources (books,courses) to learn Java for somebody who already knows what simple data structures,all kinds of loops and OOP is and won't have to spend time re-reading it all over again.
