            "name": "Fish",
        },
        {
            "_id": "Second",           
            "count": 6,
            "name": "Meat"
        },
        {
            "_id": "Third",            
            "count": 8,
            "name": "Vegetables"
        }
    ]
}

Answer 1

Inserting a group of documents from the mongo client shell:

let,

var input = {
    "docs": [
        {
            "_id": "First",           
            "count": 4,
            "name": "Fish",
        },
        {
            "_id": "Second",           
            "count": 6,
            "name": "Meat"
        },
        {
            "_id": "Third",            
            "count": 8,
            "name": "Vegetables"
        }
    ]
}

Inserting the docs array:

db.collection.insert(input["docs"]);

This would insert each item in the docs array as separate documents in the collection.

db.collection.find();

would give us, three different documents that were inserted.

{ "_id" : "First", "count" : 4, "name" : "Fish" }
{ "_id" : "Second", "count" : 6, "name" : "Meat" }
{ "_id" : "Third", "count" : 8, "name" : "Vegetables" }

To do it in Java, you need to load and parse the JSON file using JSON parsing libraries such as Jackson parser, get the docs array and persist it.
