Weather Station: Factory Methods in Records (JavaBasics_Task_397_V0.1)

📖 Description

Weather monitoring systems often encounter heterogeneous data sources. This project demonstrates the use of Static Factory Methods within Java Records to handle data conversion. By implementing the fromFahrenheit() method, the Temperature record gains the ability to encapsulate complex conversion logic while maintaining its primary focus as a Celsius data carrier. This approach improves API clarity and ensures that conversion formulas are centralized within the relevant data model.

📋 Requirements Compliance

• Data Encapsulation: Created a Temperature record to store values in degrees Celsius.
• Factory Logic: Implemented a static method for Fahrenheit conversion using the standard formula.
• Precise Calculation: Handled temperature conversion to demonstrate the relationship between different scales.

🚀 Architectural Stack

• Java 16+ (Records, Static Methods, Mathematical Logic)

🏗️ Implementation Details

• Temperature: A record with a specialized factory method for scale conversion.
• WeatherLauncherApp: The entry point for testing the boiling point conversion (212°F to 100°C).

📋 Expected result

100.0
