public class Woeid_JSON2Woeid_Apex {

    public class Place {
        public String woeid;
    }

    public class Query {
        public Integer count;
        public String created;
        public String lang;
        public Results results;
    }

    public Query query;

    public class Results {

    }

    
    public static Woeid_JSON2Woeid_Apex parse(String json) {
        return (Woeid_JSON2Woeid_Apex) System.JSON.deserialize(json, Woeid_JSON2Woeid_Apex.class);
    }

   
}

I am new in apex please tell me how to write test class for 100% code coverage and how to write it's test cases to debug and check our code is 100% correct working.

Please reply me.

hello ,
Please check my snopshot for more description http://awesomescreenshot.com/070543dx79 i want to fetch lead city name and pass to my custom controller method on page load of lead record i.e if lead city name is mumbai then my visual force page which is located in left sidebar also show mumbai.

Thanks in advance

suppose this is my  vf page https://c.ap2.visual.force.com/apex/multi_weather and in want to autopopulate the Form value i.e when the page is load the one read that i was insert in it before the record value is autopopulated in it without passing id in the url.
i am new in apex and visual form my aim is to make a setting page in which the page accept values at first time and when the second time user go to the url https://c.ap2.visual.force.com/apex/multi_weather the saved value will be autopopulated

Thanks

For example if i want to get news feed from facebook by graph api and apend these JSON data feed into the div by visualforce pages then how is it possible please explain the procedure i am new in salesforce and apex

I am done this task in php demo link :- http://joomla25.webkul.com/facebook-display/facebook-wall-feed.html
