How to clear all input fields within a JPanel

Question

Is there a way to clear all input fields (JTextField, JComnboBox, etc) after record submission within a JPanel ?

Currently what I do is, to access to each component and individually use the setText(""), etc.

You can get the components recursively, starting with the `JPanel`. — Maroun, Feb 03 '14 at 09:59
@ᴍarounᴍaroun Good call on the recursive part. Here is an [example](http://stackoverflow.com/a/21494050/418556) of doing that. — Andrew Thompson, Feb 03 '14 at 10:15
@AndrewThompson Your examples are so good that even if I don't need this method, I still use it ;) — Maroun, Feb 03 '14 at 10:16

Maybe something like so:

for(JComponent control : parentPanel.getComponents())
{
    if(control instanceof JTextField)
    {
        JTextField ctrl = (JTextField) control;
        ctrl.setText("");
    }
    else if (control instanceof JComboBox)
    {
        JComboBox ctr = (JComboBox) control;
        ctrl.setSelectedIndex(0);
    }
}

This should iterate over each component within the JPanel and check if the component is a JTextField or a JComboBox and reset accordingly.

Also you could user an index -1 to reset a JComboBox:

JComboBox ctr = (JComboBox) control;
ctrl.setSelectedIndex(-1); //-1 indicates no selection
