In Java, every class has constructor, so Applet class also has constructor which is invoked when Applet object is created by browser or Applet Viewer. Usually we don't need constructor as we don't create Applet object.
To write applet we write our own class that extends Applet, so our class also becomes Applet. Our class can also have constructor. From our class we can call super class (Applet) constructor. Look at following code:
import java.applet.Applet;
import java.awt.Graphics;
/*
<applet code="AppletConst" width=400 height=300>
</applet>
*/
public class AppletConst extends Applet {
public AppletConst() {
super(); // no compilation error : means Applet class has constructor
System.out.println("Applet constructor");
}
public void paint(Graphics g) {
g.drawString("Hello world!", 50, 25);
}
}
