how to change inputted string to double?

If I'm inputting a number in string format using JOptionPane.showInputDialog, how do I convert the string I inputted to a double?

String rate;
double hrRate;

rate= JOptionPane.showInputDialog("Input hourly rate");

String rate;
double hrRate;

hrRate= (new Double(JOptionPane.showInputDialog("Input hourly rate"))).doubleValue();


So you are creating a Double object here and then asking for the double value of that object.

You can also do:

Code:

---

String rate = JOptionPane.showMessageDialog("Enter a number");
Double hrRate = Double.parseDouble(rate);
