I have a question for you guys. I dont undertstand what the task = (A,B,C,...) can be completed during a level only if it has no dependencies or all its dependencies have been completed. Dependency = (A,B) indicated that task A has to be completed before B.

A task list = a list of all tasks to be completed.

A dependency list = a list of all dependencies considered.

So, how can I aware to write these in Java?
