Where do I add a 'finally' statement?

[Squirrel RJ]

import java.io.*;
import javax.swing.JOptionPane;

public class MyType
{
public static void main(String[] args)
{
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;

while(!done)
{
try
{
String message = "What's My Type?" +
"\n\n1) String\n2) Integer\n3) Double\n4) Quit the program\n\n";

choice = Integer.parseInt(strChoice);

if (choice<1 || choice>3) throw new NumberFormatException();
else done = true;
}

switch(choice)
{
case 1:
System.out.println("You are correct");
break;

case 2:
choice = Integer.parseInt(strtryInt);

case 3:
choice = Double.parseDouble(strtryDouble);

case 4:
done = true;

}
return choice;

catch(numberFormatException e)
{
outputLabel.setText("Try Again.");
}

}

}
}

Not sure what you're up to but putting finally block is after catch(es)

try {...} catch (...) {} [...] finally {...}

Note the [...], catch can be one or more block on even a single try. Example would be

try {...} catch (...) {...} catch (...) {...} catch(...) {...} finally {...}

What are you trying to do? the catch block must follow by the try block. Ant the capital status of each viriable does metter unlike vb.
return choice;
what is that for?

Remember nothing can go between the try and catch clause... unless it's a comment.

you have lots of problems:
1- This is a void (doesn't return a value)
2- try-catch are separated
3- you aren't using the break in each case of the switch
4- most vars are being used without initialization
5- you are throwing Exceptions without deinfing your main with a "throws"
6- you are importing java.io.* and not using it

Answering your question... you can add the finally statement after the catch(){}

How do I initialize my varibles?

I realize this is very very beginner stuff, but I have to learn somewhere.

[nebulom]

You mean, String strChoice = ""

?

How do I initialize my variables?

I realize this is very very beginner stuff, but I have to learn somewhere.

By giving an initial value to variables and calling constructors for objects
