Problem with Java Code

Posted: Nov 29, 2003 11:27 AM

I have a problem with my code...I am trying to create a JFrame that
holds names and phone numbers in a file. This works ok it is just my
output, I do not get the phone number I have entered. For Example
when I enter 1234567899 as the phone number my output is
96000990209E-308. I think is has something to down with the following
segment of my code:

public void actionPerformed(ActionEvent e1)
{
double phoneNums;

try
{
phoneNums = Double.parseDouble(num.getText());
ostream.writeUTF(name.getText());
ostream.wr iteUTF(num.getText());
ostream.writeDouble(phoneNums);
name.setText("");
num.set Text("");
}
catch(NumberFormatException e2)
{
System.err.println("Invalid Phone Number");
}
catch(IOException e3)
{
System.err.println("Error writing to file");
System.exit(1);
}
}
}

Can someone please take a look at it and let me know.

Use Strings to handle Phone Numbers rather than Double.
