Making a Hash of it - HELP PLEASE!

Question

I have declared a HashMap in a class.
I want to retieve the information stored in that HashMap from another class.
I have tried casting but JBuilder keeps throwing out error messages.... I can retrieve information from a HashMap declared in the same class so what step am I missing????
Please help as it's driving me insane....................
Thanks

Answer 1

Here is the code used to print out the HashMap details from the class that it was declared in:-
public void airlineDetails ()
String airlineName, output;
output = "I hold details about the following airlines\n";
Airline tempAirline;
//Create Iterator
Iterator airline = airlineList.values().iterator();
//Create output
while(airline.hasNext())
tempAirline = (Airline)airline.next();
output = output + tempAirline.getAirlineName() + " \n";
//display contents
JOptionPane.showMessageDialog(null, output, "Recognised Airlines",
JOptionPane.INFORMATION_MESSAGE);
I now want to print out details of a HashMap in this class but it was declared in another class ie there is an association.... The HashMap that stores the information that I want to retrieve is in the Airline class. This is my attempt which is not working at the moment...
public void displayFlight()
String output, userChoice, flightChoice, flightNum;
output = " ";
Flight tempFlight;
int choice;
//Display Flight
Iterator aFlight = flightList.values().iterator();
//Create output
while(aFlight.hasNext())
tempFlight = ((Airline)(aFlight.next())).toString();
output = output + ((Airline)(theFlights.toString()));
output = (Airline.getTheFlights()).get(flightNum);
// display contents
JOptionPane.showMessageDialog(null, output, "Flight List Contents",
JOptionPane.INFORMATION_MESSAGE);
Error messages state that flightList not fouund in Airline Reservation Class (correct it is in Airline Class) and incompatible types found java lang string required Flight
aFlight is the object declared in another method and stored in the HashMap
