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(); }

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
