 ## Included in java-util:
 - **ArrayUtilities** - Provides utilities for working with Java arrays `[]`, enhancing array operations.
-
 - **ByteUtilities** - Offers routines for converting `byte[]` to hexadecimal character arrays and vice versa, facilitating byte manipulation.
-
 - **ClassUtilities** - Includes utilities for class-related operations. For example, the method `computeInheritanceDistance(source, destination)` calculates the number of superclass steps between two classes, returning it as an integer. If no inheritance relationship exists, it returns -1. Distances for primitives and their wrappers are considered as 0, indicating no separation.
