Hello everyone

So i found out how to connect the arduino to my java program. But using the seriel connections dosent give any useful data back, its either in the wrong format, or just sends it as a box. I've looked at the related questions posted early in here, but none of the tips seems to help. So does anyone know how to send the data between an arduino and a computer using the serieal port?

P.S I've used the sample code from the arduino.cc homepage to connect to the serial port.
