ArrayLists and Large Data Sets Quiz

What is a primary advantage of using an ArrayList over a traditional array?

• ArrayLists have a fixed size.

• ArrayLists cannot insert or delete elements.

• ArrayLists allow dynamic resizing and easier element manipulation.

• ArrayLists require manual reordering of elements.

Why might it be more challenging to use an array compared to an ArrayList when dealing with large data sets?

• Arrays provide methods for easy insertion and deletion of elements.

• Arrays automatically adjust their size based on data volume.

• Arrays have a static size, which may limit flexibility in managing data.

• Arrays are less concerned with privacy issues.

What should students focus on when working with large data sets and ArrayLists according to the text?

• The individual results of computations.

• The amount of time it takes for code to run.

• Only the syntax of ArrayList methods.

• The graphical representation of data.

During the AP Computer Science exam, what type of ArrayList operations might students be asked to perform?

• Only creating and deleting ArrayLists.

• Traversing and modifying ArrayLists, including handling out-of-bounds errors.

• Focusing solely on syntax without understanding functionality.

• Writing theoretical essays on data structures.

What is the primary purpose of rewriting code from a previous unit using an ArrayList in Activity 1?

• To test the code in a new IDE

• To identify and correct errors by comparing the old and new code

• To demonstrate the use of conditional statements

• To enhance the graphical user interface
