java - Transform json recursively -


i novice in java , looking way transform json recursively,i using library json.org andi have tried many things without success .

if know , in advance.i not know how code

here json:

   “dates”:{          “date”:“2017-08-05”,        “data”:[             “date”:{                “date”:“2017-08-07”,              “values”:[                     {“value”:78},                   { “value”:56 }              ]           },           { “value”:57 }   ]   }

the output need :

“dates”:{      “date”:“2017-08-05”,     “data”:[          “date”:{            “date”:“2017-08-07”,          “values”:[               { "value”:78 }       // valeur 1  separated                   ]       },    “data”:[          “date”:{            “date”:“2017-08-07”,          “values”:[               { “value”:56 }// valeur 2  separated          ]       },        {“value”:57 }    ] }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
