(http://www.ietf.org/rfc/rfc4122.txt) The documentation for UUID says :

For UUID version 4, clock sequence is a randomly or pseudo-randomly generated 14-bit value.

For UUID version 4, the node field is a randomly or pseudo-randomly generated 48-bit value.

So, is it ok to grab random octets from a Version 4 UUID if I am looking for a randomly generated String of length 12 in java? I understand the chances of collision (duplicates) are higher but would it be a decent way to generate random strings?

If you're looking to generate random strings, there are much better ways than using a uuid. – CollinD Nov 12 '16 at 20:40
