Create a GUID / UUID in Java

What are some of the best ways to create a GUID / UUID in Java?

Have a look at the UUID class bundled with Java 5 and later.

For example:

• If you want a random UUID you can use the randomUUID method.

• If you want a UUID initialized to a specific value you can use the UUID constructor or the fromString method.
