Json Web Token example for Java

Question

Is there a sample program in Java of HPW to create header, claim set for JWT (service account ) so that I get the Access token?

The following URL looks close:
https://developers.google.com/accounts/docs/OAuth2ServiceAccount#libraries
But I was looking for any sample program to start with.

Does anyone have any help links?
