problem with parseDouble numberformatexception...

Hey! I'm trying to convert a value in a string to a double value, but I get the NumberFormatException...

tempString = readerStrings.get(i);

tempString.substring(tempString.lastIndexOf("=")+1);

tempDbl = Double.parseDouble(tempString);

here's the error

Exception in thread "AWT-EventQueue-0" java.lang.NumberFormatException: For input string: "period=360.0"

as you can see, the tempString when it is read from readerStrings is period=360.0. then i make the string only 360.0 and then I convert it to a double variable. I don't know why I'm getting this error as it looks fine to me. Please help! Thanks!

tempString = tempString.substring(tempString.lastIndexOf("=")+1);

Strings are immutable -- substring *returns* the string.

Look at your line:

tempString.substring(tempString.lastIndexOf("=")+1);

Does it do anything to tempString? Look at the String API subString method? Does it mutate the String that calls it? or does it rather return a result? hmmmmmmm

Also look at your error message, is it being passed your expected truncated string? hmmmmmm again.

You're close, but not there.

Addendum: too slow again!!

Yes, but I bow to your superior Socratic rigor, even the moment of beard twirling when you say "hmmm..."

LOL. At least we both agreed on the error. That means that we can't be right.

Besides, I thought that you'd be too busy w/ beatjunkie to answer any other questions on the forum. Guess not.
