Java ArrayList

In Java, an ArrayList is a dynamic data structure that extends the functionality of arrays. Unlike traditional arrays, ArrayLists can dynamically resize themselves, allowing you to add or remove elements without worrying about the size.

ArrayLists are part of the Java Collections Framework and are available in the java.util package.
