Java help: do all inputs using JOptionPane have to be strings?

[BigToque]

I want to enter a number, but when I enter the number, can I set the entered number to be assigned to a double? Or do I have to use parseDouble()?

if they entered a double then you need to parse a double out

set the joptionpane to a string numberStr lets say. Then do this

number = Double.parseDouble(numberStr); That will convert to a double.

I haven't used Java in awhile, but I'm 95% sure that JOptionPane only accepts strings (thus if you need a double, you have to parse it). Look in Sun's docs if you want to be absolutely sure.

just do

double number;

number = Double.parseDouble(JOptionPane.showInputDialog(null, "blah"));

it'll do the JOptionPane and the parsing all in one line of code

yeah. it only takes strings. you have to convert it as others said.
