illegal start of expression

[Don Williams]

The following errors are what I'm getting when I compile this program. Can you help, no matter what I try, it still comes up error.

Thanks

Look for mismatched curly braces real close to your error messages. Do you have an editor that can format code or identify matching (or non-matching) braces? If not, maybe the gang will recommend one.

[fred rosenberger]

look carefully at the braces in your public boolean read() method

[Rudy Rusli]

I think you have too much open curly braces in public boolean read().
Also, I think you should remove one of the curly braces at the very bottom.

[Steve Fahlbusch]

And no having two methods with the same name in a class that differs only by the return value - think like the compiler - what will be returned by a read()? a boolean or a double?

[Don Williams]

Thanks for the help.

[stephen shields]

well rudy rusli is correct you do have errors with your curly brases
there is an extra "{" after keyboard k = new keyboard();
indent your braces and you should always be able to catch one out of place.
also let the java ide insert them for you

That will be the next error. The fun never ends.
