   The *Collection framework* consists of all interfaces and classes that can hold a set of values (similar to [arrays](https://docs.oracle.com/javase/tutorial/java/nutsandbolts/arrays.html)). **ArrayList** is a class that is in this hierarchy and known as a _**Collection object**_. It implements the *List* interface which in turn implements the *Collection* interface. This *Collection* interface can be found in the `java.util` package. You will need to import this package.
