Core Java Programming Course- The Universally Unique Identifier (UUID) Class

The video tutorial explains the concept of universally unique identifiers (UUIDs) and their importance in ensuring uniqueness. It demonstrates how to generate UUIDs using Java's UID class and displays them using a for loop. The tutorial highlights the characteristics of UUIDs, such as being a 128-bit alphanumeric value, and concludes with a summary of their usefulness in Java programming.

Why are random numbers not suitable for generating unique identifiers?

• They are too complex to generate.

• They can result in duplicate values.

• They are not supported in Java.

• They are too slow to compute.
