Java Getting Bytes

Hi to all. This is my first time beeing in a forum and my first time writing in englisch, so I hope you'll appologize my bad speeking/writing... I work with Java 1.6. My Problem: I'd like to get a lot of datasets from a sensor. I get them in a ByteArray in this way : Byte: 1 | 2 | 3 | 4 | 5 | 6 |...
