Master wrapper classes with this AP CSA practice question. ArrayLists require objects, so primitives are automatically wrapped (autoboxing) and unwrapped (unboxing). Integer wraps int, allowing seamless ArrayList operations with numeric...

AP CSA Unit 4.6: File Processing and ArrayList ...
Master file processing concepts with this AP CSA practice question. When reading from a file into an ArrayList, the list grows dynamically—its size equals the number of items read. Understanding...

AP CSA Unit 4.5: Find Maximum Algorithm Practice
Master the find-maximum algorithm with this AP CSA practice question. Start with the first element as max, then compare each subsequent element and update when larger. This classic pattern appears...
