Throw an UnsupportedOperationException for FileUtils()

[yashvi2399]

Describe the technical debt
An empty method, especially if it lacks comments or clear documentation, might indicate an intentionality issue—it becomes unclear whether the method was intentionally left empty or if it's a placeholder that needs implementation.

Proposed solution
Make it a constructor and Throw an exception if this constructor is accidentally called from within the class.
