method Chain and Overloading

In this problem, you will create a program that implements overloaded format methods — one that returns a string as-is and another that converts it to uppercase when the boolean flag is true — and displays the results to standard output.

Learning Objective: Understand flexible method design using overloading

Create a string formatter with multiple format options.

Specifications

• format(String text) method: returns as is
• format(String text, boolean uppercase) method: converts to uppercase if true
