Exercises for Java Fundamentals?

Hi there,

I just started the Java Fundamentals course (lecture 12 of types), and I was wondering if there are exercises to complement the theory with practice.

I am not sure if it makes sense at all to already start writing some basic code, or if I should keep up with theory.

At what point of the course should we start with some active practice?
I would really like to hear your thoughts.

If you rely on theory you will understand only theory but try doing theory+code you will understand the working of java program …
