How to write using hash map in this mongodb query using java

Here is the Java code for the query in OP. You may need to change the collection name and database name accordingly in the below code.

MongoDB Java Driver Version = 3.2.2

import org.bson.Document;

import com.mongodb.MongoClient;
import com.mongodb.client.FindIterable;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import com.mongodb.client.model.Filters;

public class GetDataFromMongodbUsingElemMatch {
    public static void main(String[] args) {

        MongoClient client = new MongoClient();

        MongoDatabase database = client.getDatabase("localhost");

        MongoCollection<Document> userCollection = database.getCollection("users");

        FindIterable<Document> users = userCollection.find(Filters.elemMatch("assignedMember",
                Filters.and(Filters.eq("userId", "54782bfce4b086cb31d51dd5"), Filters.eq("status", "ASSIGNED"))));

        for (Document user : users) {
            System.out.println(user.toJson());
        }

        client.close();

    }

}

Test document used for testing this code:-

{
    "_id" : ObjectId("583805ac204e6a612ebaf7e0"),
    "assignedMember" : [ 
        {
            "userId" : "54782bfce4b086cb31d51dd5",
            "status" : "ASSIGNED"
        }
    ]
}

Output:-

{ "_id" : { "$oid" : "583805ac204e6a612ebaf7e0" }, "assignedMember" : [{ "userId" : "54782bfce4b086cb31d51dd5", "status" : "ASSIGNED" }] }
