Core Mindsets for Java Desktop Developers

1. The UI is for the User

Always put yourself in the end-user's shoes. The interface must be intuitive, easy to understand, and efficient. A good design minimizes errors and increases user productivity.

2. Think in Events

The application's flow is not sequential but is driven by user actions. Think in scenarios: "When the user clicks this button, what should happen?"

3. Separate Logic from UI (MVC/MVP)

Avoid writing complex business logic directly in event handlers. Use patterns like MVC to separate data handling from the UI, making the code more maintainable.

4. Multithread for a Responsive UI

Never perform time-consuming tasks (like database queries, API calls) on the main UI thread. Use multithreading to keep the application smooth and responsive.
