Multiple JTextField in JPanel with scroller

JPanel panel = new JPanel();

panel.add(new JTextField(25);

panel.add(new JTextField(25);

..

JScrollPane scrollPane = new JScrollPane(panel, 100, 100);

The two numbers (100 and 100) is the size that the scroll pane will show, so you can change these if you need a different size. If the panel is larger than this dimension, it will have scroll bars so you can scroll to all the text fields.

Thanks clairec666 for response, now its giving me the following exception

java.lang.IllegalArgumentException: invalid verticalScrollBarPolicy

Below is my code.

Please have a look, what mistake I am doing here?

Check the API for the JScrollPane constructors. The second and third argument in this constructor new JScrollPane(panel, 100, 100);

does not set the size of the scroll pane, but rather the vertical and horizontal scrolling policies. There are only a fixed set of valid policies (if this class had been written today these two arguments should have been enums), and 100 is not one of them.
