using buttons and checkboxes

I need to use a single button and some checkboxes in my program. I have implements ItemListener in the header to use the checkboxes but how do I get the button to work. It needs to clear the text field. Do I need to implement the ActionListener some how?

Thanks!

    Yes, you need to implement the ActionListener. This requires the actionPerformed(ActionEvent e) method, in which you can clear the text field (= set the text of the text field to an empty string). The button has a method called addActionListener() to link the ActionListener to it.

    Ok, how do i do that when my header is as follows:

    public class PetAdviceApplet extends Applet implements ItemListener

    I used the ItemListener so I could use the checkboxes as well. How do I use both checkboxes and a button. When I try to put the addActionListener() in with my button in the init() method I get an error that it cannot be applied?

    Any ideas?

    Thanks again!!!!

    You can add more than 1 interface to a class:
    [code]
    public class PetAdviceApplet extends Applet implements ItemListener, ActionListener
    [/code]

    Thankyou so much! That's the only thing I've been struggling with. Thanks again! God Bless!!!
