Universal Control Panel: Interface Collision (JavaBasics_Task_354_V0.1)

📖 Description

In modular systems, different interfaces may occasionally define methods with identical signatures. This project explores how Java handles Interface Method Collisions. By implementing both InterfaceA and InterfaceB, which both declare a doAction() method, the MultiAction class provides a single unified implementation that satisfies both contracts simultaneously. This demonstrates the efficiency of Java's type system in resolving overlapping behavioral requirements.

📋 Requirements Compliance

• Independent Contracts: Created InterfaceA and InterfaceB with identical doAction() method signatures.
• Unified Implementation: Developed the MultiAction class to fulfill both interfaces with a single method body.
• Contract Synchronization: Proven that a single action can satisfy multiple distinct architectural protocols.
• Clean Execution: Verified that the combined implementation produces consistent output regardless of the interface context.

🚀 Architectural Stack

• Java 8+ (Interface Inheritance, Method Overriding, Contract Resolution)

🏗️ Implementation Details

• InterfaceA: The first control protocol requiring an action.
• InterfaceB: The second control protocol with an identical action requirement.
• MultiAction: The concrete class that merges both protocols into one execution.
• RemoteLauncherApp: The entry point for testing the unified action.

📋 Expected result

Action performed for both interfaces.
