Answer / rohit chhabra
usualy applets hv no contructors coz we do't need to create
object of the applet class...
but if one wants to create an object of an applet class,
create it in static block...This block execute before init
method..

Answer / sunil dhadwe
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);
}
}

Answer / urusa
Applets do not have constructors because we don't need to create the object of the applet class....so its justified that it is true that applets usually do not have constructors

Answer / roy antony arnold
Don't say like this....
Answer:
Applets don't usually have constructors because an applet
isn't guaranteed to have a full environment until its
init() method is called. For example, the Applet image
loading methods don't work inside an applet constructor, but
can be called from the init() method.

Answer / therathna
In Java For Every Class we can provide constructors so
o busily we can provide constructors for applets.
u Don't ask like this type of questions because we can
pratically found these questions when done programs
u ask only questions like which are not practically unable
