The following example generates a random UUID. We can get the version number associated with the specified UUID. It is used to get the variant associated with the specified UUID. It returns a String object representing this UUID. It returns a timestamp value associated with this specified UUID. It returns a node value that is associated with the specified UUID. It retrieves a version-3 (name-based) UUID based on the specified byte array.

It returns the most significant 64 bits of this UUID's 128-bit value. It returns the least significant 64 bits of this UUID's 128-bit value. It generates a UUID from the String representation. The method compares this object to the specified object. The method compares the UUID with the specific UUID. It returns the clock sequence value associated with this specified UUID. The class generates an immutable UUID that represents a 128-bit value. It extends the Object class and implements the serializable and comparable interface. Java UUID Classįor generating the UUID, the Java programming language provides the UUID class. The above-discussed layout is valid only for variant 2. The variant field holds a value that identifies the layout of the UUID. The LSBs consists of the following unsigned fields: The MSBs consists of the following unsigned fields: There are many variants of the UUID but Leach-Salz variant is widely used.

  • In a web application it can be used to generate session IDs.
  • Widely used in a cryptographic application.
  • It can also be used to generate transaction IDs.
  • It is used to generate unique URN (Uniform Resource Names).
  • The use of UUID depends on the situation, use cases, complexity, and conditions. It is also known as a Globally Unique IDentifier (GUID). A UUID is 36 characters (128-bit) long unique number.

    It is a part of the Distributive Computing Environment (DCE).

    UUIDs are standardized by the Open Software Foundation (OSF). UUID stands for Universally Unique IDentifier.

    In this section, we will discuss what is UUID and how to randomly generate UUID (version 4) in Java. It consists of hex-digits separated by four hyphens. 代码示例来源: origin: is a widely used 128-bit long unique identification number in the computer system. Return timeBasedGenerator(ethernetAddress, (UUIDTimer) null) Public static TimeBasedGenerator timeBasedGenerator(EthernetAddress ethernetAddress) * No additional external synchronization is used. * variant 1 (time+location based), using specified Ethernet address * Factory method for constructing UUID generator that generates UUID using 代码示例来源: origin: cowtowncoder/java-uuid-generator /** Public static TimeBasedGenerator timeBasedGenerator() This first method creates a version 3 UUID from the given byte array: UUID uuid UUID.nameUUIDFromBytes ( byte bytes) Second, the randomUUID () method creates a version 4 UUID. 代码示例来源: origin: Activiti/Activiti protected void ensureGeneratorInitialized() which will use one of available For convenience, there are three static methods to create a UUID. You may check out the related API usage on the sidebar. Additionally it can also be made externally synchronized with other. As all JUG provided implementations, this generator is fully thread-safe.

    Since no Ethernet address is passed, a bogus broadcast address will be constructed for purpose of UUID generation usually it is better to instead access one of host's NIC addresses using EthernetAddress#fromInterface which will use one of available MAC (Ethernet) addresses available. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. Implementation of UUID generator that uses time/location based generation.
