Need Sample Java Code to use VRA 7.x/6.x Java SDK

Hi,

I am planning to use VRA 7.x/6.x Java SDK to do following operations for environment provisioning:

1. Create/Update VM from template.
2. Create load balancer and attached VMs.
3. Connect VM using SSH via java code.

I am referring VRA 7.x Java SDK and java API documentation from below URL:

https://developercenter.vmware.com/web/sdk/7.0.0/vrealize-automation

There are 1000 of classes created under package "com.vmware.vcac.*". I am unable to find out sample java code which will give me an idea about, How to use Java SDK classes for environment provisioning using VRA?

Can anyone provide me any reference document which will help me to do so?

Thanks,

Mitul Shah
