java - Loop Json array with gson -


im trying parse jsonobject , can't seem it, here got.

 json = (json data)  jsonparser parser = new jsonparser();  jsonobject rootobj = parser.parse(json).getasjsonobject();  jsonobject paymentsobject = rootobj.getasjsonobject("payments");   for(jsonobject pa : paymentsobject){         string dateentered = pa.getasjsonobject().get("date_entered").tostring();     } 

but foreach not applicable type missing. i've tried different ways can't seem it. thanks

json

 {  "name":"test 2",  "amountcollected":"1997",  "payments":[   {      "quoteid":"96a064b9-3437-d536-fe12-56a9caf5d881",      "date_entered":"2016-05-06 08:33:48",      "amount":"1962",            },   {      "quoteid":"96a064b9-3437-d536-fe12-56a9caf5d881",      "date_entered":"2016-05-06 08:33:08",      "amount":"15",            },   {      "quoteid":"96a064b9-3437-d536-fe12-56a9caf5d881",      "date_entered":"2016-05-06 03:19:08",      "amount":"20",            }  ] } 

now can see data, can see payments is in fact array (values uses []).

that means need call rootobj.getasjsonarray("payments") returns jsonarray, , iterable<jsonelement>, means loop should for(jsonelement pa : paymentsobject).

remember, each value of array can type of json element (object, array, string, number, ...).

you know jsonobject, can call getasjsonobject() on them.

json = (json data) jsonparser parser = new jsonparser(); jsonobject rootobj = parser.parse(json).getasjsonobject(); jsonarray paymentsarray = rootobj.getasjsonarray("payments"); (jsonelement pa : paymentsarray) {     jsonobject paymentobj = pa.getasjsonobject();     string     quoteid     = paymentobj.get("quoteid").getasstring();     string     dateentered = paymentobj.get("date_entered").getasstring();     bigdecimal amount      = paymentobj.get("amount").getasbigdecimal(); }
