包支持：org.json.jar

第一个：

String js = "{'a':'111','b':'333','c':'666'}";
   try {
    JSONObject jsonObject01 = new JSONObject(js);
    String a = jsonObject01.getString("a");
    String b = jsonObject01.getString("b");
    String c = jsonObject01.getString("c");

    System.out.println(a+b+c);
   } catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
   }

第二个：

String json = "{'name': '呵呵','array':[{'a':'111','b':'222','c':'333'},{},{'a':'999'}],'address':'上海'}";
   try {
    JSONObject jsonObject = new JSONObject(json);
    String name = jsonObject.getString("name");
    String address = jsonObject.getString("address");

System.out.println("name is:" + name);

    System.out.println("address is:" + address);

    JSONArray jsonArray = jsonObject.getJSONArray("array");

    for (int i = 0; i < jsonArray.length(); i++) {
     System.out.println("item " + i + " :" + jsonArray.getString(i));
    }
   } catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }
