Short values in distributed systems without requiring synchronization The fact that UUIDs can be used to create unique, reasonably Unique numeric identifiers across a network can easily become aīurden. In such cases, "auto increment" schemes often used byĭatabases do not work well, as the effort required to coordinate Stems from the increasingly distributed nature of modernĪpplications. One area UUIDs have gained popularity is as database keys. Modern applications have a need to create and utilize UUIDsĪs the primary identifier for a variety of different items in complexĬomputational systems, including but not limited to database keys,įile names, machine or system names, and identifiers for event-driven Many things have changed in the time since UUIDs were originallyĬreated.

Let’s see the code snippet below: package We can also get the version and the variant of the UUID using the version() method and variant() method respectively. To obtain the value of the random string generated we need to call the UUID.toString() method. The UUID.randomUUID() method return a UUID object. To generate UUID in Java we can use the class. Some of its usage are for creating random file names, session id in web application, transaction id and for record’s primary keys in database replacing the sequence or auto generated number. UUID / GUID (Universally / Globally Unique Identifier) is frequently use in programming.
