JSONObject obj= new JSONObject(str.toString());
Iterator x = obj.keys();
JSONArray jsonArray = new JSONArray();
Map<String, String> map = new HashMap<String, String>();
while (x.hasNext()) {
for(int i=0;i<obj.length();i++) {
LOG.info("=============");
String key = (String) x.next();

Directly put JsonObject i.e. obj into jsonArray
直接把JsonObject即obj放入jsonArray
jsonArray.put(obj);
//result is [{ "abc":"test","bed":"cot","help":"me"}]
Final code
最终代码
JSONObject obj= new JSONObject(str);
JSONArray jsonArray = new JSONArray();
//simply put obj into jsonArray
jsonArray.put(obj);
//result is [{ "abc":"test","bed":"cot","help":"me"}]

It works for me.
这个对我有用。
JSONObject obj = new JSONObject(result.toString()); JSONArray arr = obj.getJSONArray("value");
JSONObject obj = new JSONObject(result.toString()); JSONArray arr = obj.getJSONArray("value");
