4. How do I convert byte[] to String?    forums.oracle.com

Your problem is that you're assuming a newline actually indicates the end of a line. Assuming you can't fix the sender (or yell at the maintainer and get him to fix it), take advantage of the fact that you know what a valid line starts with and just ignore the newline characters. Thanks but that gives me the same result. I ...

23. String to Byte conversion and back yield different results    forums.oracle.com

1.) Don't ever use the getBytes() method (or the String(byte[]) constructor) unless you know exactly what it does. Always use the variant(s) that take a encoding. 2.) Don't try to convert an arbitary byte-array into a string. That won't work (and if it worked it wouldn't produce an readable string anyway). If it's encrypted byte[] data, then keep it in a ...

25. convert Byte[ ] to string    forums.oracle.com

Sounds like an encoding problem to me. chars in java are 16 bits, so if you break them up into 8 bit bytes, the encoding has to stay in the correct order.

28. How to convert bytes to long and vice versa?    forums.oracle.com

Start by explaining clearly exactly what you mean by "convert bytes to long." There are literally infinitely many ways to do that. Will it always be 8 bytes? Is it 8 bytes in big-endian, 2s-complement format? Then, explain how you would do it "manually." Then clarify what part of translating those manual steps to Java you're having trouble with.
