Help with program plz (long code)

Question

anyone know how i can fix these 2 errors:
Driver2.java:47: code is already defined in main(java.lang.String[])
String code = JOptionPane.showInputDialog(
^
Driver2.java:51: incompatible types
found : java.lang.String
required: int
int val = bc.getCode();
^
the case 2 in the driver is where it messes up, i believe..it works with just the case 1...any help/advice is appreciated(i am aware of spacing errors)
import javax.swing.JOptionPane;
import java.util.Scanner;
public class Driver2
   public static void main(String[] args)
      String userChoice;
      int choice;
Scanner keyboard = new Scanner(System.in);
userChoice = JOptionPane.showInputDialog("Enter 1 to enter a numeric zip code:\n"
+ "Enter 2 to enter a bar code:\n"
+ "Enter 3 to exit program:\n");
choice = Integer.parseInt(userChoice);
while (choice != 3)
       switch (choice)
       case 1:
       String input = JOptionPane.showInputDialog( "Please enter a five-digit zip code: ");
int num = Integer.parseInt(input);
BarCode bc = new BarCode(num);
String code = bc.getCode();
JOptionPane.showMessageDialog(null, "The barcode of the zip is: " + code);
System.exit(0);
break;
case 2:
String code = JOptionPane.showInputDialog( "Please enter bar code: ");
int val = bc.getCode();
if (val >= 0)
System.out.println("The zip code is: " + val);
else
System.out.println("Incorrect bar code data");
System.exit(0);

> i got it to compile now...i can toy around w/
it..thanks for the help
Good.
Stick with this handle, ok?I must say I am not thrilled with
a) when I questioned the first post of WhiteSox asking if it was bugz or a classmate or what I was ignored by the OP
b) I guess the OP is trying to distance himself from his very first thread where somebody did part of his homework for him with results that are now plainly evident. As I predicted at the end of the last thread.

I hope that matsabigman and others who help homework posters by doing it for them will take note of the results of this help thus far. Not much good has come of this.
BigMan/WhiteSox I am still detecting a fundamental lack of basic concepts on your part. This is the underlying cause of your compile errors but those are only a symptom. You can continue treating the symptoms but it would be a better use of your time to treat the disease, which in this case means spending some time getting a better grasp of Java fundamentals.
