parse JSON with gson and GsonBuilder()

Question

String jsons = "{'appname':'application', 'Version':'0.1.0', 'UUID':'300V', 'WWXY':'310W', 'ABCD':'270B', 'YUDE':'280T'}";

This is my json string. How can i parse it to GsonBuilder() that i will get object back? I try few thinks but none works.

I also read https://sites.google.com/site/gson/gson-user-guide

public class YourObject {
   private String appname;
   private String Version;
   private String UUID;
   private String WWXY;
   private String ABCD;
   private String YUDE;
   //getters/setters

}

parse to Object

YourObject parsed = new Gson().fromJson(jsons, YourObject.class);

or

YourObject parsed = new GsonBuilder().create().fromJson(jsons, YourObject.class);

minor test

String jsons = "{'appname':'application', 'Version':'0.1.0', 'UUID':'300V', 'WWXY':'310W', 'ABCD':'270B', 'YUDE':'280T'}";
YourObject parsed = new Gson().fromJson(jsons, YourObject.class);

works well

EDIT
in this case use JsonParser

JsonObject object = new JsonParser().parse(jsons).getAsJsonObject();
object.get("appname"); // application 
object.get("Version"); // 0.1.0

what about without new class? I don't need new class – senzacionale Nov 09 '12 at 11:42
@Ilya Is it possible to get the output as ArrayList rather than YourObject.. Please look http://stackoverflow.com/questions/30163699/google-map-direction-api-using-retrofit .... I need ArrayList as output of the retrofit.. – zacharia May 12 '15 at 07:41

JSON uses double quotes ("), not single ones, for strings so the JSON you have there is invalid. That's likely the cause of any issues you're having converting it to an object.

so i need to check json string if is valid. Is try catch enought? – senzacionale Nov 09 '12 at 11:50
@senzacionale That depends on whether or not it throws an exception if you pass it invalid JSON; I assume that it would, so using a try-catch block should be sufficient. – Anthony Grist Nov 09 '12 at 13:44
