Illegal start of type; identifier expected problem.

[Kathleen Tillman]

Hi all,
I'm having a problem with my java program. I am trying to make a program where the user enters a product number and a quantity, then at the end of the program the total of the order pops up. I have gotten as far as the last statement on my code without compilation errors, but when I try to display the total it either won't show up (if I move it up a bracket) or I get a compilation error. Can someone possibly help me with this? Thanks!

	JOptionPane.showMessageDialog(null, "The total is: " + orderAmount);	
}

The error I get is this:

(I apologize if I didn't format the errors correctly.)

Hi,


the error causing because the line
"JOptionPane.showMessageDialog(null, "The total is: " + orderAmount);"

is in Class not in method main.

Please enter this in main method,
this would solve your problem.

Thank you so much for your help. The last time I moved it up a line, I forgot to press "-1" to exit, so I thought it wasn't working.

Thanks!!

Does that mean I need to move it farther down or farther up? And wouldn't that screw up showing the total after the information has been entered? I'm really new to Java, so this may sound like a really dumb question, but I'm confused.
Thanks.

Last line of your code is out of the main method...

Welcome to JavaRanch

We have all had that sort of error ourselves. All lines of code have locations they can be put in, and (usually) places they can't. That line is a statement, so it has to be inside a method (or initialiser block, or constructor). In this case, it fits a method. You will also notice that you have got about 9 messages, all caused by the same error. You will get used to that soon enough.
