Understand the Problem

The questions ask about dynamic arrays and ArrayLists in Java, including definitions, implementations, syntax, and properties of dynamic arrays compared to static arrays.

More Information

Dynamic arrays automatically resize when they need more space, making them more flexible than static arrays, which have a fixed size.

Tips

Remember that dynamic arrays can grow or shrink as needed, unlike static arrays.
