String randomUUIDString = uuid.toString() Creating a random UUID (Universally unique identifier). GUIDs are often used in databases, and they are generated by a. The term GUID is typically used in software development, and it refers to a unique identifier that is generated to identify a specific component or object. A GUID is a 128-bit number used to identify resources in computer systems. Let’s see the code snippet below: package GUID is an acronym for Globally Unique Identifier. We can also get the version and the variant of the UUID using the version() method and variant() method respectively. Alternatively, you can extend io. and bring the implicits into scope that way. To obtain the value of the random string generated we need to call the UUID.toString() method. You will now have the UUID type and object available: scala> classOf UUID res0: Class io. class. So what you need is to create this array from your Date, Int & Int. The UUID.randomUUID() method return a UUID object. 1 If you are talking about (I suppose Scala uses this Java object under the hood) it's possible to create UUID on a base of some array of bytes with nameUUIDFromBytes (byte name). 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. scala> UUID.random res1: io. 5f4bdbef-0417-47a6-ac9e-ffc5a4905f7f scala> UUID(1, 2) res2: io. More bits are used in this version, so there are fewer UUID combinations. These can be created using a random or pseudo-random number generator. Although the random UUID uses random bytes, four bits are used to indicate version 4, while two to three bits are used to indicate the variant. UUID / GUID (Universally / Globally Unique Identifier) is frequently use in programming. This version of UUID is generated randomly.
