How challenging is it to learn the Java programming language? What can you do with it?

Turing complete in Java. Anything that can be written is fair game. Although the core Java language is simple to learn, some more recent additions are more complicated. Learning the language itself typically takes no longer than a few weeks.

However, creating a fully functional programme in Java is uncommon. Applications typically include a GUI to communicate with users, a connection to a DBMS package for data retrieval and storage, etc. The libraries that deal with handling web request processing or communicating with a DBMS are extensive and quickly become very complex. In the interactions of these complex libraries, errors must be handled correctly.
