Java UUID

In Java, a UUID (Universally Unique Identifier) is a 128-bit identifier that is typically used to uniquely identify information in distributed systems. The UUID class in Java provides a convenient way to generate random UUIDs. The randomUUID() method within this class generates a new UUID using a cryptographically strong pseudo-random number generator. This means that the generated UUIDs are highly likely to be unique across different systems and time, making them suitable for various applications such as unique key generation, distributed system synchronization, and database record identification. Using UUID.randomUUID() allows developers to easily incorporate randomness and uniqueness into their Java applications without the need for external libraries or manual implementation. UUID can be used to generate a session ID by creating a new UUID when a user initiates a session. This session ID serves as a unique identifier for the user's session, allowing the server to associate and manage the session data.
