Hello, I am a programmer with great experience in java, the concept of blueprint and the line of execution I understand but my question is if I should learn c ++? with blueprints can you do the same as with c ++ or are there things that can’t be done? I don’t know where to focus my efforts on whether to advance in blueprints or learn the syntax of c ++ because I see that with blueprints the tasks are done much faster, but I don’t know if it will be incomplete
Thanks a lot!
Start with Blueprint and when you feel comfortable with it and if you have any interest in C++ start to combine C++ and Blueprint to get the best of both worlds. Blueprint is capable of nearly everything but you will be looking at an endless mess of wires at times that could have easily been done in C++ but that is the sacrifice many are willing to make to stay away from the complexity of C++.
If you are making a multiplayer game with a dedicated server you will need some C++ sooner or later.
Learn both!
And don’t stop there either… Create your own libraries, make your own systems and build your own editor tools as well 
Everything contributes to the learning process, but start with Blueprints of course.
