Generating 8-Char UUIDs in Java

The UUID class in Java generates UUIDs of 36 characters in length. However, if you only need 8-character UUIDs, you can use the following code:

String uuid = UUID.randomUUID().toString().substring(0, 8);

This code generates a random UUID using the UUID.randomUUID() method and then uses the substring() method to extract the first 8 characters of the UUID.


Generating 8-character UUIDs in Java is a simple task that can be accomplished using the UUID class and the substring() method. This solution provides a quick and easy way to generate unique identifiers in your Java applications.
