Heyho,
I worked through the entire Java course. But my problem is that I don't know how and where to start with the practical tasks. I lack the practical knowledge there, so to speak. What to do?
Nobody can teach you creativity, and problem solving is a skill you develop. Learning the syntax of a programming language does not grant you creative powers. Just as your ability to read and write does not make you a great author, novelist, poet, or songwriter.
You also need to understand that the SoloLearn course only teaches the basic syntax of Java. The Java API contains over 5,000 classes so that will give you some idea of how little Java you actually know.
The SoloLearn course is the equivalent of the first term of the first year of primary school. You wouldn't expect such a student to be suitably qualified for work would you?
Software engineering and design is a whole different discipline to punching out code at a keyboard.
