Advanced Printing System: Overloading vs Overriding (JavaBasics_Task_313_V0.1)

📖 Description

Understanding the distinction between Overloading and Overriding is fundamental to mastering Java. This project implements an Advanced Printing System where a ColorPrinter utilizes both concepts. The base Printer class provides overloaded methods to handle different data types (int and String). The ColorPrinter subclass then overrides the specific print(String) method to provide specialized "colored" output. This demonstrates how subclasses can inherit certain behaviors while selectively modifying others to suit specific requirements.

📋 Requirements Compliance

• Base Overloading: Implemented two print methods in the Printer class with different parameter types.
• Subclass Overriding: Specialized the print(String) behavior in ColorPrinter while maintaining the exact method signature.
• Inheritance Utilization: Proven that the subclass can still access the non-overridden print(int) method from the parent.
• Dynamic Behavior: Verified that the program correctly selects the appropriate method at runtime based on the object type and parameters.

🚀 Architectural Stack

• Java 8+ (Inheritance, Method Overloading, Method Overriding)

🏗️ Implementation Details

• Printer: The base engine providing multi-type printing capabilities.
• ColorPrinter: The specialized engine that redefines string output logic.
• PrintingLauncherApp: The execution entry point simulating the system's usage.

📋 Expected result

Number: 5
Colored string: Hello
