java - How can I conditionally deserialize JSON nested objects? -


i have list of json objects have following format:

 [   {    "id":1,    "type":"plane",    "data":{            "wingspan":10           }   },   {    "id":2,    "type":"train",    "data":{            "carriages":5           }   } ]

i have following java object

class transportation {   int id;   string type;   genericdata data; }  class planedata extends genericdata {   int wingspan; }  class traindata extends genericdata {   int carriages; }

i need parse json java objects mentioned above. how create list of transportation objects field data instance of appropriate genericdata child objects can determined value of 'type' field.

i have been learning neural networks , genetic algorithms, , test learning, have tried make ai learns play flappy bird: i have left running @ least 10 hours (overnight , longer), fittest member still fails show significant advancements in intelligence when began simulation apart avoiding floor , ceilings. inputs rays (as can see above) act sight lines, , network fed in lengths, , birds vertical velocity. seems best bird ignoring sight lines except horizontal one, , when short, jumping. output number between 0 , 1, if output larger 0.5, bird jumps. there 4 hidden layers, 15 neurons each, input layer feeding forward first hidden layers, 1st hidden layer feeding forward 2nd 1 ... , final hidden layer feeding forward output, dna of bird array of real numbers representing weights of neural networks, have made project using same style of neural network, , genetic algorithm, in ants had travel food, , worked perfectly. here code: https://github.com/karan0110/flappy-bird-ai please ...
