Java 8 (or above) We simply can write String.join(..), pass a delimiter and an Iterable, then the new StringJoiner will do the rest:OP's code is taking the native UUID, which is 16 bytes, and converting it to base 64. He should end up with a 24-byte string, which is longer than the 16 bytes he started with but shorter than the normal 36-character UUID string. So the answer to OP's original question is yes, you'll maintain uniqueness. level 2. A GUID or (UUID) is a universally unique identifier which is a 128-bit number or (16 byte long).
