Details

To meet Java code standards, I made a few changes to method and class-level variables:
Added a Lombok no-arg constructor with private access to restrict the user from creating a new object of the class, since this class consists of all static methods.
Added override annotations to improve the readability of methods and removed additional code from lambda expressions.
