I have a simple calculate code that count about box volume (long * width * height):
ActionListener volListener = new ActionListener() {
    public void actionPerformed(ActionEvent e) {
        try{
            String L = long.getText();
            String W = width.getText();
            String H = height.getText();
            double parseL = Double.parseDouble(L);
            double parseW = Double.parseDouble(W);
            double parseH = Double.parseDouble(H);
            double volResult = parseL*parseW*parseH;
            txtAreaOut.append("Volume : " + volResult + "\n");
            long.setText("");
            width.setText("");
            height.setText("");
        }catch(NumberFormatException nfe){
            String fault = nfe.getMessage();
            infoBox(fault,  " " + nfe.getClass());
        }
    }
};
If "volResult" return large number, for example 9.0408284742E7, and i want the result like this 9.040.828.474...
How the code?..
