Yes, that right filtering is done by extends FilterOutputStream or FilterInputStream, but this Adler32 is for de-coupling the process of filtering. so whe you create filtering class you have class Adler32 to help you to do anything you want when filtering class overide read and write method

Filtering is done by the classes that extends FilterInputStrean and FilterOutputStream, there is not any filtering done by Adler32. It just updates the checksum given it was read a char or an array. Anyways, if you still want to keep the adler32 part you don't need to touch it. You just need to be sure that update() be called after you change to uppercase.
