here we r getting the problem with ut data and get data????????????

java implementation of put and get method

import java.util.*;
public class Menus{
private ArrayList keys;
private ArrayList values;

  public Menus(){
    keys = new ArrayList();
    values = new ArrayList();
    }
  public java.util.Set keySet(){
    return new TreeSet(keys);
    }
  Hashtable<String,String> hash = new Hashtable<String,String>();
  public Object get(Object k){
        int i = keys.indexOf(k);
        if(i == -1)
         return null;
        return values.get(i);
    }
  public Object put(Object k, Object v){
        for(int i=0; i < keys.size(); i++){
          Object old = keys.get(i);
          Enumeration keys = hash.keys();
          while(keys.hasMoreElements()) {
              Object key = keys.nextElement();
              Object value = hash.get(key);
            }

        }
        keys.add(k);
        values.add(v);
        return k;
          }
          public static void main(String[]args){
              Menus menu=new Menus();
              menu.put("1","Rose");
              menu.put("2","India");

          System.out.println(menu.get("1"));
          System.out.println(menu.get("2"));
          }
}
