Utility Class

Definitions

1. A class that contains only static methods and no instance state, serving as a namespace for related helper functions. Common in Java (e.g., Collections, Math, StringUtils), utility classes typically have a private constructor to prevent instantiation.

   In plain English: A collection of handy helper functions grouped together under one name, used like a toolbox rather than a blueprint for creating objects.

   Example: "StringUtils.isBlank() saves us from writing the same null-and-whitespace check in every controller."
