UUID (Universally Unique Identifier) is a globally Unique Identifier. It is a 128-bit long number and generally expressed in hexadecimal notation.

The core idea of the algorithm is to generate a UUID Based on the machine's Nic, local time, and a random number. UUID is a new class in 1.5.

In java. util, you can use it to generate a globally unique ID. The unique defect of UUID is that the generated result string is long.
