public class vi extends java.applet.Applet{
public void init(){}
public void start()
{
Button b = new Button("start");
add(b);
add(b);
add(b);
}
}
Why is button added only once??
Thanx in advance

Only one button appears because you've created only one button and added it 3 times.

One more thing related to this is , even if u add da same component to many diff containers , even in this case only to da last container to which dis component is being added ,component actually get added .
I somehow don had time to xplore more into dis , so i just remember these 2 points

There are no questions about Applets on the SCJP 2 exam.
Good luck,

Applet is a container just like Panel, Frame, Window & etc. You need to know the basics for sure!

We DO knw the basics , da class hierarchy !
N dats y i linked the Lenna's applet prob wid my foll statement
" even if u add da same component to many diff containers , even in this case only to da last container to which dis component is being added ,component actually get added "
So can u , wid all ur basics in place , tell da reason for above stated behaviour?

You have created only one button and adding it 3 times. Of course only one button will appear.
