Initiating SkyReserve System with Development Setup & Workflow Design

Business Scenario

Welcome Developers!

In the previous lab, we installed the Java Development Kit (JDK), which gave our computer the ability to understand and execute Java programs.

However, writing Java code directly in the Command Prompt is not convenient for building real-world applications.

Your next task is to set up a professional development environment using Eclipse IDE. Once the setup is complete, you'll write and execute your very first Java program—Hello World!—marking the beginning of your software development journey.
