       public InvalidTypeException(String pDetailMessage) {
           super(pDetailMessage);
       }
   }

   Repeat the operation for two other exceptions: NotExistingKeyException of type Exception and StoreFullException of type RuntimeException.

   public class Store {
       ...
       public native int getInteger(String pKey)
           throws NotExistingKeyException, InvalidTypeException; public native void ...
