How to get all stacks, Apps and Instance Ids using AWSOpsWorks client using Java

I am new to AWS OpsWork, I have to get all stack, App and Instance ids from an AWS account using the Java AWS SDK.

I tried with AWSOpsWorksClient, but I couldn't find how to get stack ids using that. Also, I have to delopy a project on all the instance on the particular APP.

Could someone help on this?
