Template method Pattern: Document Processing

In this problem, you will create a program that implements the Template method Pattern by defining a fixed processing flow with a final method in the abstract class DocumentProcessor, then overriding each step in the subclass PDFProcessor, and displays the result to standard output. Read a document name from standard input and use it as the filename in the save step.

Learning Objective: Fix processing flow with final method

Create a document processing system. Define the processing flow with a final method in the DocumentProcessor class, and customize each step in the PDFProcessor class. Read a document name using Scanner and pass it to processDocument(String documentName).
