java - How to delete mongodb document with two conditions one with $gt operator? -


i retrieve following information:

delete database name = 'aaa' , age>20; 

but mongodb in java. essentially, should delete document contain word aaa , age greater 20 in them. know there $in operator in mongodb, how do same in java, using java driver? i've been trying everywhere getting nothing. i've tried:

query = new basicdbobject("age", new basicdbobject("$gt", "20"), new basicdbobject("name", "aaa")); 

json want delete this.

{"school" : "newschool" , "name" : "aaa" , "age" : "50"} 

what want find-term:

{    "name" : "aaa",    "age" : { $gt : 20 } } 

construct basic db object, or use new 3.x filters create bson you. (as use 3.x, here's appropriate example):

mongoclient client = ... mongodatabase db = client.getdatabase(...); mongocollection<document> coll = db.getcollection(...); coll.deletemany(filters.and(filters.eq("name", "aaa"), filters.gt("age", 20)));
