writing basic queries for appengine's datastore

I have been looking around for some simple plain examples that demonstrate :

submitting data to datastore
retrieving data from datastore
updating data in the datastore
deleting data from the datastore

Are there some good tutorials with java that demonstrate this or may be any one can explain/demonstrate it here ?

The official documentation has pretty much everything you need to get started. The exact page you will need is this one.
