Tasks in Java

Question

Java

Hello!
Please advise a site where you can find tasks for learning Java programming with a system for checking results with tests.

Thank you.

Answer 4

In my opinion, applied programming is far from the Olympiad, which is sharpened for algorithms and input-output, when in applied the lion's share of efforts is the interface + technologies and most often simple algorithms (but not everywhere).
At one time, I took the usual applied task for the work that I had to do and implemented it in the language I was learning.
One of the tasks was a MAC address scanner in your subnet, try to write. It can definitely be written.
