The HelloWorld applet shown next is a Java class that displays the string "Hello World".
Following is the source code for the HelloWorld applet:
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
public class HelloWorld extends JApplet {
//Called when this applet is loaded into the browser.
public void init() {
//Execute a job on the event-dispatching thread; creating this applet's GUI.
try {
SwingUtilities.invokeAndWait(new Runnable() {
public void run() {
JLabel lbl = new JLabel("Hello World");
add(lbl);
}
});
} catch (Exception e) {
System.err.println("createGUI didn't complete successfully");
}
}
}
An applet such as this is typically managed and run by the Java Plug-in software in the browser.
