Having fun with Pi4J and JBang on the Raspberry Pi
summary
Shows a runnable single Java file that uses JBang to fetch dependencies and Pi4J to talk to hardware, demonstrated on a fresh Raspberry Pi where JBang installs Java 11 and pulls Maven deps automatically. The demo maps GPIO pins to Java objects so an LED blinks and a button shortens blink delay and after 5 button presses the program exits, proving the loop works. Notes that Pi4J exposes GPIO as Java objects but requires sudo for native access and includes native libraries for I2C/SPI/serial.
