Question

I am able to create JFormatted TextField that accepts only float values,but I am not able to fetch that value….
I am declaring it ..

stopAppFormattedTextField = new javax.swing.JFormattedTextField(new DecimalFormat("#.00"));

and fetching the value using :

double stop=(Double)stopAppFormattedTextField.getValue();

but the above statement is throwing the following exception:

“Exception in thread
“AWT-EventQueue-0″
java.lang.ClassCastException:
java.lang.Long cannot be cast to
java.lang.Double”

what should I do to fetch float values?
-Thanks in advance

You’re getting Longs from the formatter, but you want doubles. You can do this:

Number number = (Number)stopAppFormattedTextField.getValue();
double stop = number.doubleValue();
