Why would you use an ArrayList instead of an array?

  1. ArrayList can only store objects

  2. Arrays can dynamically resize themselves

  3. ArrayList automatically resizes itself

  4. Array elements can be accessed using foreach syntax

The correct answer is: ArrayList automatically resizes itself

Array elements have a fixed size and cannot dynamically resize themselves while the size of an ArrayList can increase or decrease automatically. ArrayList also allows for the storage of different types of objects whereas arrays can only store objects of the same type. Additionally, the foreach syntax can also be used for ArrayLists to simplify the process of accessing its elements.
