how to add new value in existing array.As i shown below;
Desire Output:

    "_id" : ObjectId("5822d0c92f136292e5e4a0cc"),  
    "Age" : "five",   
    "details" : [   
                 {  
                    "Name" : "abc"

                }  
            ]      
}

And with this code, i am getting this output:- 

db.c1.update({"_id" : ObjectId("5822d0c92f136292e5e4a0cc")},
{$push:{"details":{"Name":"xyz"}}})

"_id" : ObjectId("5822d0c92f136292e5e4a0cc"),
"Age" : "five",
"details" : [

    Your desired output is not making any sense. you can't have an **Object** that contains more than 1 similar key. please refer this question http://stackoverflow.com/questions/13987365/how-to-insert-an-element-to-mongodb-internal-list – molaga Nov 09 '16 at 08:00
