How to retrieve a class from a map function ?

Question

I have a class which I add to Map Function something like this
import java.util.*;
public class DataStorage
     private Map<String, StoreData> callRecords = null;
     public void StoreCalls(String callOrigin, StoreData sd)
          callRecords = new HashMap<String, StoreData>();          
          callRecords.put(callOrigin, sd);
     public Map<String, StoreData> getDataStorageMap()
          return callRecords;
}Now If I want to retreive the data using the Map how should I do it.....

You really need to study that tutorial. The answers are there, but in the case of Maps, keys are unique:
map.put("unqiue", obj1);
map.put("unique", obj2); //"unique" no longer maps to obj1 -- unless obj1 == obj2!
