遍历jsonArray和jsonObject

String str = "[{name:‘a‘,value:‘aa‘},{name:‘b‘,value:‘bb‘},{name:‘c‘,value:‘cc‘}]" ; 
JSONArray json = JSONArray.fromObject(str ); 
if(json.size()>0){
  for(int i=0;i<json.size();i++){
    JSONObject job = json.getJSONObject(i);  
    System.out.println(job.get("name")+"=") ;  
  }
}

JSONObject jsonObject = new JSONObject(jsonString);
Iterator iterator = jsonObject.keys();
while(iterator.hasNext()){
    key = (String) iterator.next();
    value = jsonObject.getString(key);
}
