trying to connect to a kubernetes cluster created with tools/operator using java SDK

I am super new to fabric. Can someone please point me to how i would go about connecting a java app using the fabric java SDK ? I can contribute a sample app as a PR if that would be something people can use.

I am trying to make sense of [this](https://github.com/hyperledger/fabric-samples/blob/master/asset-transfer-basic/application-java/src/main/java/application/java/EnrollAdmin.java#L29) fabric-samples java project. I noticed the operator generates connection profiles and ca certs for all orgs. However its not clicking how my client can talk to the cluster stood up by the operator using those generated files.

Can anyone help ?
