Question

I have a raffle draw program that used to have many commands and components, etc.
But I would like to make it a lot simpler by omitting many commands or components such as buttons or labels.
When I tried to do so, errors arose (42 errors) all of which say:

error: class, interface or enum expected.

Can somebody help me track down these errors?

BTW, here’s my code (UPDATED):

            cons++;
            if(cons==2)
            {
                lbachieve.setText("You're a GOOD GUESSER!");
                userscore=userscore+20;
            }
            else if(cons==4)
            {
                lbachieve.setText("You're an AMAZING GUESSER!!");
                userscore=userscore+50;
            }
        }
        else if(boo==true)
        {
            cons=0;
            life--;
            lblives.setText("life: "+life);
            lbcons.setText("cons: "+cons);
        }

    }

}
    public static void main(String[] args)
    {
        app.init();
    }
}

I can’t figure out which of these lines make the errors arise.

Answer 1

The problem is you’ve got too many closing braces at the end of your enormous (300+ lines!) actionPerformed method. That means you’re closing your class declaration, leading to the subsequent errors.

To avoid this problem in the future:

• Get your IDE to indent your code. Your indentation goes wonky on line 156 to start with (just below the declaration of option2) and also on line 382 (just below the declaration of options1). It’s distinctly odd in other places too.
• Keep your methods much, much shorter. When a method start taking more than about a page to display, you should really be looking to refactor it into smaller methods. (Ideally, earlier than that – I like methods which are fewer than ~20 lines, personally, although I don’t have a hard and fast limit.) Methods of the size of your actionPerformed one are a maintenance nightmare.
