Converting a string to a double

[Token]

I am trying to make a calculator program with GUI and stuff and i have all my keys working but all i need is to do the calculations part. when you press a number or the decimal key it adds the number or decimal to the end of a String, like a calculator does. but in order to do the calculation I'll need to convert this String to a Double, and i cant do that with

code:

Double.parseDouble(string)

because i'm using RTP. please help

thanks

I used the same command in RTP, and it worked perfectly fine for me. Perhaps you forgot to assign that value to something, like this:

code:

double = Double.parseDouble (string);

What version of RTP are you using?

Version 1.0.6

Yah, Assigned it to a variable, but it didnt work, i couldent find it in the double class in my help file so i'm guessing its not with my version.

so no one can think of any other commands?

Don't use RTP. Download the JDK from Sun and there won't be any question about your environment being borked.

If it's being graded in school, it'll be by a teacher with the same crummy version of RTP.

It's bizarre that your version is so old though. Current ver is 1.7 - and it's not exactly new.

code:

Double.valueOf (double d).doubleValue ()

tada! all thanks to http://javaboutique.internet.com I looked at a copy of a calculator program they made and found that little tidbit of greatness. Thanks for your help, and heres my (semi finnished) applet.
