parseDouble Problem

[henri henri]

Hello,
Below is the printout in Netbeans of my JavaBean ouput. The last value was typed in the TextField was 5.1 for the audio value. I have tested it may times and it always come out as 0.0
Further down is the code to parse my String to a double from the TextField.
If I need a double, ddoes the user need to type it in with a decimal point in between two numbers. Would anyone guess why it comes out as 0.0?

Here is a link to a screenshot to give you an ideaof what it is I am working on. Thanks.

         String audio1 = audioBox.getText();
       try {
         double audio2 = Double.parseDouble(audio1);
       } catch(NumberFormatException nex) {
         JFrame fr = new JFrame();
         JOptionPane.showMessageDialog(fr, "Entrez un chiffre dans la     bo�te de saisie 'Audio'.",
         "Avertissement!",  JOptionPane.WARNING_MESSAGE);
       }

This line

double audio2 = Double.parseDouble(audio1);

declares a local variable and initializes it. Since the block it's in ends immediately after, nobody ever uses this variable. Perhaps there's also a member variable named audio2 that you're trying to assign to? In that case, you need to remove the "double", which turns this from a declaration of a new variable into a simple assignment to an existing variable.

Thank you for your response. It is quite mind-boggling. I will try your suggestion.

It turns out it was an oversight of mine. I had declared my double twice. Once as a member and then inside a try.block

Yep. Isn't that what I said?
