String randomUUIDString = uuid. Creating a random UUID (Universally unique identifier). 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. Generates either a version 4 (random) or version 5 (named) RFC 4122-compliant UUID as a formatted string.

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. Using UUID.randomUUID () The simplest way to create a UUID in Kotlin is to use the UUID.randomUUID () function. We will be using the Kotlin UUID library, which is available in the Kotlin Standard Library. To avoid concerns related to linking the identifier across apps, store GUIDs in internal storage instead of external (shared) storage. fromString(name: String) Creates a UUID from the string standard representation as described in the toString method. Creating a UUID in Kotlin is straightforward and can be done with a few lines of code. UUID / GUID (Universally / Globally Unique Identifier) is frequently use in programming. Kotlin Java var uniqueID UUID.randomUUID().toString() Because the identifier is globally unique, it can be used to identify a specific app instance.
