Module Initialization: Static Lifecycle (JavaBasics_Task_260_V0.1)

📖 Description

In large-scale applications, some operations must occur exactly once when a component is first introduced to the system. This project explores the Static Initialization Block. Unlike constructors, which run every time an object is created, the static block runs only once — when the Java Virtual Machine (JVM) loads the class into memory. This mechanism ensures that the global state, such as moduleStatusMessage, is prepared before any instance-level logic begins.

📋 Requirements Compliance

• Static Initialization: Implemented a static { ... } block for one-time setup.
• Class Loading Trigger: Demonstrated that instantiating a class triggers its static members first.
• Controlled Output: Ensured the status message is printed directly from the static context.
• Encapsulation: Used a static field to store the module's readiness state.

🚀 Architectural Stack

• Java 8+ (Static Blocks, Class Loading Mechanisms, JVM Lifecycle)

🏗️ Implementation Details

• Module: The system component containing the self-initializing logic.
• SolutionApp: The entry point that triggers the class loading process.

📋 Expected result

Application: The main module is ready to work!
