Java Rookie looking for help compiling

**MJD4** · July 14th, 2009, 12:41 PM

Can anyone tell me why this won't compile. Error " reached end of file while parsing" which probably means that the brackets are not paired. I got to the point where I was sticking brackets everywhere just to see if it would work. Need help. I have attached the java file.

Please post the code in [Code ] [/code ] tags.

(format them without spaces, i.e.)

Code:

public class SomeClass {

}

Not many people will bother extracting your application to look at the syntax.

Sorry, I don't know what "Put your code inside

If you indent your code with a consistent style it will make it a lot easier to see where the problem is.

Look at each of the if statements, while statements etc and make sure each code block associated with the statement has exactly one opening and one closing bracket. Then do the same for each method and finally the class, deleting spurious brackets/adding missing brackets as you go.

figured your error with the JOptionPane

you have

Code:

income = JOptionPane.showInputDialog(null, "Enter your income for the year.");
			income = Double.parseDouble(inputIncome);

and I blieve you want

Code:

inputIncome = JOptionPane.showInputDialog(null, "Enter your income for the year.");
			income = Double.parseDouble(inputIncome);

that seemed to fix that

**MJD4** · July 15th, 2009, 07:01 AM

Thanks, that was an error in the code. I still get a "PrepareTax.java:151: reached end of file while parsing" error though. I'm sure that it has something to do with the brackets.

**MJD4** · July 15th, 2009, 07:46 AM

Sorry I didn't read the post prior. I think that did fix the bracket issue and the problem in the JOption pane. Now it cannot find symbol class TaxReturn, so almost there.
Thanks a lot, I was pretty frustrated.

**ncr7** · July 15th, 2009, 08:02 AM

Your going to have to make a class TaxReturn inorder to get rid of that cannot find symbol class TaxReturn unless you already have it in another file.

**blink002** · July 15th, 2009, 01:13 PM

How did you make out with class TaxReturn?? Doing same course and i think this is quite complicated being an introductory coarse...............

**MJD4** · July 15th, 2009, 02:26 PM

I am still struggling with it, especially the syntax with having to do all the data validation that is required. There is a lot of validation to do for a intro course. We are using Java Programming 4th edition by Joyce Farrell. I assume you are too. I find that the exercises are not well supported by the chapters. All the code in the book does one thing, and then the exercise asks you to do multiple things without an example to go by.
I have learned more off the internet than in the course.
How are you doing?
