From Java Object to JSON String using javax.json -

is possible create json string list<myclass> using java ee 7's javax.json library without iterating on list<myclass>?

this , performance unacceptable 2000 iteration. suggestion?

list<myclass> items = mydb.getallitems(); jsonobjectbuilder builder = json.createobjectbuilder(); builder.add("success", true); jsonarraybuilder childrenarraybuilder = json.createarraybuilder();  (myclass item : items) {      childrenarraybuilder.add(         json.createobjectbuilder()             .add("id", gettreenodeid(item) + "-" + (idsplit[1]))             .add("nodestatus", b)             .add("text", item.getname())             .add("leaf", false)); } 

you creating lot of objects in loops not necessary. gson , far myclass contains need like:

list<myclass> list = mydb.getallitems(); gson gson = new gson(); string mystring = gson.tojson(list);
