How to update GCP instance object using java SDK?

I want to add more data disks to existing VM instance object using java SDK. Below are my sample code:

 Compute.Instances.Get getinstance = compute.instances().get(projectId, zone, instanceName);
 Instance instance = getinstance.execute();
 AttachedDisk dataDisk = new AttachedDisk();        
    dataDisk.setSource("projects/project/zones/zone/disks/diskName");
    dataDisk.setType("PERSISTENT");
    dataDisk.setMode("READ_WRITE");
    dataDisk.setAutoDelete(true);
   instance.getDisks().add(attacheddisk);

But I didn't see any method in compute service for update/put.Can any one help on this. I know how to do update the instance by using Rest API,But i want do this by java sdk.

You can attach instance using methods of Compute.Instances class only. These methods will update the instance during execution.

AttachedDisk dataDisk = new AttachedDisk();        
dataDisk.setSource("projects/project/zones/zone/disks/diskName");
dataDisk.setType("PERSISTENT");
dataDisk.setMode("READ_WRITE");
dataDisk.setAutoDelete(true);

//attach disk to instance

Compute.Instances.AttachDisk attachDisk=compute.instances().attachDisk(projectId, zone, instanceName, dataDisk);

To attach multiple disk, I don't think there is any method exposed in java API. You would have to call attachDisk()

To check LUN AttachDisk class provides getIndex(), where 0 is reserved for boot disk. Check the link for more information on LUN in GCP.
