    Default Help on Float Values

    Hi,

    I am a beginner in Java and I am currently learning about JOption pane. I have this below question plz.

    Using Strings I am accepting an input from the user and by using the Interer.ParseInt(variable) option I am able to multiply this two strings using the code below.

       String Length;
       Length = JOptionPane.showInputDialog("Enter the Length");
       String Breadth;
       Breadth = JOptionPane.showInputDialog("Enter the Breadth");
       System.out.println(" Area is " + (Integer.parseInt(Breadth) * Integer.parseInt(Length)));
       System.exit(0);

    Now My question is... How Do I make my code accept Decimal values. E.g. My Code should accept 10.02 as Length and 20.42 as Breadth and give the product a Decimal. How Do I do this???

    Appreciate the help.
