mongoDB query for multiple fields in a collection

I am trying to query for multiple fields in a collection that looks like:

{ "_id" : ObjectId("54ee37f3a4cd7c1ce4483124"), "imageblock" : "http://someimage.jpg", "textblock" : "Lorem ipsum dolor sit amet, in eget aliquam, odio ut leo mi turpis a felis, adipiscing neque maecenas ac nulla nec curabitur. A hac neque magnis integer arcu ut, per bibendum, aliquet metus nec ante orci amet. Feugiat quis sit" }

What would be the best approach to retrieve the values for both the "imageblock" and "textblock" keys? Very new to working with Mongodb.

Mongo mg = new Mongo("localhost", 27017);
DB db = mg.getDB("deepdivedb");
DBCollection collection = db.getCollection("contentblocks");
BasicDBObject me = new BasicDBObject();
DBCursor cursor = collection.find();

   try {
       while(cursor.hasNext()) {
          System.out.println(cursor.next().get("imageblock"));     
          // out.print("<img src="+ cursor.next().get("imageblock") + ">");    
       }

    } finally {
       //mongoClient.dropDatabase("test");
       cursor.close();

    }

Thanks for any tips.
