How to learn Java quickly?

Question

Java

Hello! I got a problem. My computer science teacher, unexpectedly for me, sent me to the Olympiad. Today it turned out that there are only 4 programming languages: TurboPascal, Java, C++/C. From this bouquet, I decided to choose Java. How to quickly (in 2 weeks) learn Java at a good level (I already have programming experience, I work with JS and I know VBA)? Maybe someone knows some courses or will give advice?

Answer 1

Just like you were once a participant in the Olympiads.
since at the Olympiad, the most important thing is the correct execution of the task, and not competent execution (as in real development, where you will need to change your program later), and given that you are given 4 languages, then the conditions of the tasks for all 4 will be the same and simple .
course .
This course will be enough for you to get the basics of the language to perform primitive tasks, like at the Olympiad (it is unlikely that you will be required to have the correct application architecture, etc.)

Just like Neo in the matrix: "Operator, motorcycle driving skills" or whatever it was.. Well, you get the point. It doesn't happen.
