jsonarray怎么遍历,json数组遍历的几种方法

步骤

①、转为JsonArray格式
②、使用Iterator进行遍历准备

String relation = "[{"codeId":"1","codeName":"你们"},{"codeId":"2","codeName":"他们"}]"; cdzt=JSON.parseArray(relation); Iterator<Object> it = ja.iterator(); List<PubCodeModel> list=new ArrayList<PubCodeModel>(); while (it.hasNext()) { JSONObject ob = (JSONObject) it.next(); PubCodeModel model = null; if(ob.getString("codeId")!=null){ model=new PubCodeModel(); model.setVcode(ob.getString("codeId")); } if(ob.getString("codeName")!=null){ model.setVname(ob.getString("codeName")); } if(model!=null){ list.add(model); } } 关键CODE Iterator<Object> it = ja.iterator();while (it.hasNext()) {JSONObject ob = (JSONObject) it.next();}
