Hi guys) I'm just starting to learn Java and I want to become a Java developer. I don’t know what I should learn with Java to be able to get a job. Do you have any suggestions?

I just studied multithreading and I want to create something to get more unique practice, but I'm not finding any good and easy problems where I could apply multithreading. What it can be? I can’t come up with anything.

Codegym is excellent for learning the Java programming language. Being comfortable with thinking and programming in Java, the natural next step would be to study the JVM and know the machine that runs Java.
