    Default Help on Decimal Values - JOptionPane

    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.

    There are classes for other numeric data types besides Integer. Look at the Float and Double classes for methods like you are using from the Integer class.
    If you don't understand my answer, don't ignore it, ask a question.
