Answer:

Option 4: the java.util package

Explanation:

Java Array List is not imported by default and therefore we need to import java.util package. Array List is one of the Java predefined collections used to store a group of entities.

One advantage offered by Array List compared with a normal array is that an item can be dynamically added into the list without recreating a new list. Besides, array list also offered some built in methods to manipulate the elements within the list that can save a project development time.
