23. String to Byte conversion and back yield different results forums.oracle.com1.) 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 ... |

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