In the lab description, you said "Range: Constructor takes two integers, the lower and upper bounds." Does it mean the data type of lower and upper bound is necessarily "int" in Java. Is it possible that you ask for a range of [0..100_000_000_000]. (100_000_000_000 is out of bound of an int in Java)

Thank you for your help.

Yes, you can use "int". You can check the Changelog at the Assessed Lab for this error handling possibilities.

2024-04-22: You do not need to handle "user" errors such as being passed null references. This lab is an exercise in using and inheriting from abstract classes, not in error handling.
