Need help with program

**brooklyn52** · 10-05-2011, 01:58 AM

I am new to enumerated data types and basically I have to read in a file and convert strings to enums. I need help on finding out why this wont run properly I have already made the enumerated classes which are:

Java Code:

public enum PassengerType { FIRSTCLASS, ECONOMIC }
public enum CrewType { PILOT, FLIGHTATTENDANCE }
public enum AirlineCode { AA, DL, UA, US, NW, SW }


public class HUairport2_Macklin	
{	
	public static void main(String[] args) throws IOException
	{
		PassengerType pType;
		CrewType cType;
		AirlineCode aCode;
		String line;
		String name;
		String seat;
		String letter;
		
		System.out.println("The following list consits of the passengers flying from the airport.");
      System.out.println("---------------------------------------------------------------------");   	
      System.out.println("### Flight AA ###");
		
		File file = new File("PassengerList.txt");
		Scanner inputFile = new Scanner(file);
		
		ArrayList AA = new ArrayList(); 
		ArrayList DL = new ArrayList();
		ArrayList UA = new ArrayList();
		ArrayList SW = new ArrayList();
		ArrayList NW = new ArrayList();
		ArrayList US = new ArrayList();
		
		while(inputFile.hasNext())
		{
			line = inputFile.nextLine();
			
			StringTokenizer strTokenizer = new StringTokenizer(line);
			
				letter = strTokenizer.nextToken();
				name = strTokenizer.nextToken();
				aCode = AirlineCode.valueOf(strTokenizer.nextToken());
				seat = strTokenizer.nextToken();
			
			if(letter.equals("F") || letter.equals("E"))
			{
				pType = PassengerType.valueOf(letter);
				Passenger aPeople = new Passenger(pType, name, aCode, seat);
				
				
				if(pType.equals("F"))
				{
					pType = PassengerType.valueOf("First Class");
				}
				else if(pType.equals("E"))
				{
					pType = PassengerType.valueOf("Economic");
				}
				else
					System.out.println("Error, " + pType + " is not a valid passenger type.");
				
				if(aCode.equals("AA"))
					AA.add(aPeople);
				else if(aCode.equals("DL"))
					DL.add(aPeople);
				else if(aCode.equals("UA"))
					UA.add(aPeople);
				else if(aCode.equals("SW"))
					SW.add(aPeople);
				else if(aCode.equals("NW"))
					NW.add(aPeople);
				else if(aCode.equals("US"))
					US.add(aPeople);
				else
					System.out.println("Error, " + aCode + " is an invalid airport.");
			}
			
			if(letter.equals("P") || letter.equals("A"))
			{
				cType = CrewType.valueOf(letter);
				
				Crew bPeople = new Crew(name, cType, aCode);
				
				if(cType.equals("P"))
				{
					CrewType.valueOf("Pilot"); 
				}
				else if(cType.equals("A"))
				{
					CrewType.valueOf("Flight Attendance");
				}
				else
					System.out.println("Error, " + cType + " is not a valid passenger type.");
					
				
				
				if(aCode.equals("AA"))
					AA.add(bPeople);
				else if(aCode.equals("DL"))
					DL.add(bPeople);
				else if(aCode.equals("UA"))
					UA.add(bPeople);
				else if(aCode.equals("SW"))
					SW.add(bPeople);
				else if(aCode.equals("NW"))
					NW.add(bPeople);
				else if(aCode.equals("US"))
					US.add(bPeople);
				else
					System.out.println("Error, " + aCode + " is an invalid airport.");
			}
		}
		inputFile.close();
		
				for(int index1 = 0; index1 < AA.size(); index1++)
               System.out.println("\t" + AA.get(index1));
            for(int index2 = 0; index2 < DL.size(); index2++)
               System.out.println("\t" + DL.get(index2));
            for(int index3 = 0; index3 < UA.size(); index3++)
               System.out.println("\t" + UA.get(index3));
            for(int index4 = 0; index4 < SW.size(); index4++)
               System.out.println("\t" + SW.get(index4));
            for(int index5 = 0; index5 < NW.size(); index5++)
               System.out.println("\t" + NW.get(index5));
            for(int index6 = 0; index6 < US.size(); index6++)
               System.out.println("\t" + US.get(index6));
