dev-pravakar/JAVA-Projects ? reverse-engineered prompt

Build me a small Java practice project collection with a few separate apps in it.

I want one simple ball game, one basic CRM app, and one library management app. Keep them easy to run from an IDE, with clean code, simple menus or screens, and enough features to actually use for a demo. The CRM should let me add, view, edit, and remove customer records. The library app should let me manage books and basic borrowing or return tracking. The ball game should be a fun playable desktop game with simple controls and scoring.

Please keep everything straightforward and beginner friendly, with sensible structure and comments where helpful. If it makes sense, use local storage or in memory data so the apps work without extra setup. If you need current Java best practices or library docs, look them up online.
