Answer 1

while (rs.next() && rs.first()) { 


         Map<String, String> datanum = new HashMap<String, String>(); 

         datanum.put("A", rs.getString("Id")); 
         datanum.put("B", rs.getString("OdaNo")); 
         datanum.put("C", rs.getString("bolId")); 
         datanum.put("D", rs.getString("Durum")); 
         prolist.add(datanum); 


         s = datanum.get("D"); 



        }
