Collection and Collections are both related to the Java Collections Framework, which provides a set of classes and interfaces to store and manipulate groups of objects¹.

However, they have some differences:

• Collection is an interface that represents a group of individual objects as a single unit. It is the root interface of the collection hierarchy and defines the common methods for all collections, such as add, remove, size, clear, isEmpty, etc¹.

• Collections is a utility class that provides static methods to operate on collections, such as sorting, searching, copying, reversing, etc. It also provides methods to create synchronized or unmodifiable collections².

Here is an example of using Collection and Collections in Java:
