How Can I Launch One Standalone Java Application from Another Within the Same Package?

Standalone Java Applications

Question:

How can I launch one standalone application from another in the same package while maintaining their independence?

Answer:

Starting applications directly from within another application is generally discouraged, as it violates the principle of separation of concerns. Instead, consider restructuring your design to separate the functionality of each application into reusable classes.

Explanation:

The Application class is intended to serve as the entry point for an entire application. It should be instantiated only once per Java Virtual Machine (JVM). Attempting to launch another application from within a running one can lead to errors.

To achieve your goal of having multiple independent applications, refactor your code as follows:

• Separate reusable functionality: Move the core functionality of each application into regular Java classes, independent of Application.
• Use the start method to launch individual modules: Each application can have its own start method that creates a Scene and Stage for its specific functionality.
• Instantiate modules within the parent application: In the main application, you can instantiate the desired modules as needed and display their user interfaces.

This approach allows you to keep each application independent while still having the ability to launch them from a single parent application. It also aligns better with the intended use of the Application class and promotes code reusability.
