    Post New to applets

    package appletPackage;
    import javax.swing.JApplet;
    import javax.swing.JButton;
    import javax.swing.AbstractButton;
    import java.awt.event.*;
    public class MainClass extends JApplet {
    	private JButton button;
    	private String text = "Screenflashing";
    	public MainClass(){
    	public void init(){
    		button = new JButton(text);
    	public void addActionListener(ActionListener button) {
    		button.actionPerformed(); // line erroring
    		text = "ScReEnFlAsHiNg";

    I think I've got a few things wrong, but I'm not exactly sure what to do; how do I make the addActionListener listen to my 'button' variable/buttonthing (so I can make stuff happen when the button's clicked... )?

    This has almost nothing to do with Applets, and more to do with general Swing. I'd suggest reading through the Swing tutorial (Trail: Creating a GUI With JFC/Swing (The Java™ Tutorials)), specifically this article: How to Write an Action Listener (The Java™ Tutorials > Creating a GUI With JFC/Swing > Writing Event Listeners)
