Java code examples for license management (creation, validation, deletion)

I want Java code examples for client-side license management in Creem, specifically covering license creation, validation, and deletion operations. Currently, Creem only provides TypeScript SDK and examples, but I work with Java and need to implement license management in my Java application. I would need clear, working examples showing: - How to create licenses using Java (with HTTP clients like OkHttp) - How to validate licenses from the client side - How to delete/deactivate licenses - Proper error handling for common scenarios (revoked licenses, exceeded activations, etc.) This would help Java developers integrate Creem's license management without having to figure out the API calls and JSON parsing manually. Having official Java examples would save development time and reduce implementation errors.
