What is a characteristic of using arrays in Java?

  1. They allow mixed types

  2. Their size is dynamic and can change

  3. They hold a fixed size of elements

  4. Only support object types

The correct answer is: They hold a fixed size of elements

Arrays in Java have a fixed size, meaning that the amount of elements they can hold is already defined and cannot be changed. This is what sets them apart from other data structures, such as ArrayLists, which have a dynamic size and can add or remove elements as needed. It is also worth noting that arrays in Java can only hold elements of the same type, which makes option A and D incorrect.
