Official Google Cloud Java SDK with examples

Also, is there a sample maven project illustrating Java SDK usage to create Virtual Machine /Instance ? and also an example illustrating with all dependencies needed and sample code

Looking for very similar to AWS Java SDK to create a VM like at below link https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/javav2/example_code/ec2/src/main/java/com/example/ec2/CreateInstance.java

Found this one but not sure if this is officially supported SDK. https://github.com/googleapis/google-cloud-java If there are sample to cerate VM please share.

If you want to use Maven, there is a great tutorial here and a Quickstart guide here.
