How to display de-serialized value in apex controller from wrapper class (Very Urgent)

Hi Everyone,
This is my wrapper class,
public class JSON2Apex2 {
    public class Address_components {
        public String long_name;
        public String short_name;
        public List<String> types;
    public class Geometry {
        public Location location;
        public String location_type;
        public Viewport viewport;
    public class JSON2Apex {
        public List<Results> results;
        public String status;
    public class Results {
        public List<Address_components> address_components;
        public String formatted_address;
        public Geometry geometry;
        public String place_id;
        public List<String> types;
    public class Viewport {
        public Location northeast;
        public Location southwest;
    public class Location {
        public Double lat{get;set;}
        public Double lng{get;set;}
    public Location loc{get;set;}
    public static JSON2Apex2 parse(String json) {
        return (JSON2Apex2) System.JSON.deserialize(json, JSON2Apex2.class);

This is my apex controller,
public class latlan_AC 
    static  List<Contact> contlist=new List<Contact>();
    String address;
    public  static JSON2Apex2 wrapper {get;set;}
    public latlan_AC(List<Contact> conlist)
        for(Contact cntlist:conlist)
            string jsonString = JSON.serializePretty(cntlist);
    public static void callout(String  cnt1)
        contact cnt =  (contact)JSON.deserializeStrict(cnt1, contact.class);
        String address=cnt.MailingStreet +','+cnt.MailingCity+','+cnt.MailingState+','+cnt.MailingCountry+','+cnt.MailingPostalCode;
        Http http = new Http();
        HttpRequest req = new HttpRequest();
        req.setHeader('Content-Type', 'application/json');
        HTTPResponse res = http.send(req);
            wrapper = (JSON2Apex2) JSON.deserialize(res.getBody(), JSON2Apex2.class);
            system.debug('result'+ wrapper); //Here I got null value only how to display lat and lng values
My requiremayent is to display  public Double lat{get;set;} public Double lng{get;set;} values in apex controller

Thanks in Advance,
