HelloSwing2.java

// An applet that appears on the page as a button that says
// "Click me".  When the button is clicked, an informational
// dialog box appears to say Hello from Swing.  This version
// uses an anonymous class as an ActionListener for the button.
// When this file is compiled, it produces two class files,
// HelloSwing2.class and HelloSwing2$1.class.  Both class
// files are required to use the applet.
