带有数组的嵌套HashMap，JAVA

Question

I have the following hashMap:

{"success":true,
 "message":"Profile retrieved successfully",
 "data":{
     "address":[{
        "objectId":"6ItcdQGBFu",
        "street":"6782 NW 102nd St",
        "aptSuite":"782",
        "state":"FL",
        "zipCode":"33762",
        "city":"Brickell",
        "type":"Home"},{
        "objectId":"yyRA9M2gk1", 
        "street":"7828 NW Boston Rb",
        "state":"Massachusetts",
        "zipCode":"33178",
        "city":"Boston",
        "type":"Office"}
     ]
    }
}

If I want to access the "message", I would write the following code:

    object.get("message");

Or if I wanna print it:

    object.get("message").toString();

I would like to know how can I iterate and access through the "address" objects.

Assuming this is a bunch of nested HashMaps (and "address" points to a list with one item, according to your example), you could access a value in the message through

object.get("data").get("address").get(0).get("street")

and you could iterate through all the fields by

HashMap<String, String> addressObj = object.get("data").get("address").get(0);
for (Map.Entry<String, String> entry : addressObj.keySet()) {
    String key = entrey.getKey();
    String value = entry.getValue();
    // your code here
}
