it show error

You need to copy and post the full text of error messages.

If you are having problems with mismatched {}s, some IDEs have a tool you can use to find the pairing {}s
On my IDE put the cursor just before a { and press: Ctrl and ] and the cursor will move to the pairing }.
Another way to pair {}s is to print the source on a piece of paper and use a pencil to draw lines from a { to its pairing }. Start at an inner most pair and move out.

Again, please post your code with code tags. Please look at Norm's post to see how to do this. Again, you need to put the effort in to find matches for all of your braces. Again this isn't rocket science, since all you need to do is match 'em. Please have at it.

Like this?

What does the compiler say?

Not a record, not even close.

How many errors before your last change? Restore the code to the old version and try again.

1 error: {//end computeCost
i will try again with the old version

Print the source and use a pencil to connect a { to its pairing }
Start at the inside and work out.

what source? you mean my code?

Yes, by source I meant your code before it is compiled.

i did that

And?

and do you want me to compile it

I don't know why you would wait for someone to tell you to compile the program. Compilations are free. I compile frequently when writing a program. Its better to have fewer errors with frequent compiles rather than wait and get lots of errors.

i know ,I didn't mean to and it don't worked so i have to go back to my old version and compile successfully and move on next method 1 new errors: public String updatePriceCode(String PriceCode)

You need to copy the full text of the error messages and paste them here. We're here and you're there. We can't see what is on your PC's screen.

You've coded the switch statement many times in this thread and have always had a value inside the ()s. This time you left it out and the compiler finds it as an error.

i edited my post

Which post? What did you change?

I change from switch() to switch (c). Should I put down "c" or "cost". i hope this work this time.

Read the tutorial on how to use a switch statement:
The switch Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

i did that. the compiler won't correct my error like can't find" the symbol everything i put down word or inital in it

Not yet. They are working on it. But for now the programmer has to correct his own errors.

If you need help with the errors, copy the full text of the error messages and paste it here.
