How to find documents matching multiple criteria

Question

I\'m trying to query a collection using operands AND\'d together. I\'ve got the shell version working:

db.widgets.find({color: \'black, shape: \'round\', wei         


        

Answer 1

BasicDBObject criteria = new BasicDBObject();
criteria.append("color", "black");
criteria.append("shape", "round");
criteria.append("weight", 100);

DBCursor cur = widgets.find(criteria);
