I’m using Java and I need to parse a Json string to a nested map structure or trie tree structure, The challenge is that I don’t know the detailed Json structure explicitly, which means the coming Json for example looks like:

{     "id":1,     "name":"Frank",     "Address":{     "city":"New York",     "state":"NY"},     "lastactive":01-02-2017",     "obj":{"type":"list","list":[1, 5, 6]} }  {     "id":4,     "name":"Geerry",     "Address":{     "city":"Seattle",     "state":"WA"},     "lastactive":01-04-2017",     "obj":{"type":"name","name":"myfile"},     "data":[         "onetype":[         {"id":2,"name":"John Doe"},         {"id":3,"name":"Don Joeh"}         ]     ] } 

it shares some common structure while not all of the structure are the same, so when I declare a map, I can not explicitly tell the data type, is there a way for me to handle this?
