its probably something really daft but it wont work!

[0402900]

here is the code

{
double a = double.parseDouble(txtRadius.getText());
double b = 3.14;
double c = a * b;
txtCircumference.setText(String.valueOf(c));
}

It is a small piece of code to calculate the circumference of a circle, when i compile it on netbeans I get a class error.

Any help would be appreciated!

Ta,
Steve

parseDouble is a static method of the Double class (not the double class...)
so:

double a = Double.parseDouble(txtRadius.getText());
