I have to handle two classes with identical methods but they don\'t implement the same interface, nor do they extend the same superclass. I\'m not able / not allowed to change t

    I wrote a class to encapsulate the logging framework API's. Unfortunately, it's too long to put in this box.

    The program is part of the project at http://www.github.com/bradleyross/tutorials with the documentation at http://bradleyross.github.io/tutorials. The code for the class bradleyross.library.helpers.ExceptionHelper in the module tutorials-common is at https://github.com/BradleyRoss/tutorials/blob/master/tutorials-common/src/main/java/bradleyross/library/helpers/ExceptionHelper.java.

    The idea is that I can have the additional code that I want to make the exception statements more useful and I won't have to repeat them for each logging framework. The wrapper isn't where you eliminate code duplication. The elimination of code duplication is in not having to write multiple versions of the code that calls the wrapper and the underlying classes. See https://bradleyaross.wordpress.com/2016/05/05/java-logging-frameworks/

    The class bradleyross.helpers.GenericPrinter is another wrapper that enables you to write code that works with both the PrintStream, PrintWriter, and StringWriter classes and interfaces.
