Using implements Runnable and MouseListener

[Doug van Vianen]

I am fairly new to Java but have written an applet that uses 'implements
Runnable' to do some timing
eg
public class Puzzle extends Applet implements Runnable
{ etc.

and also an applet which detects left, right and double mouse clicks using
'implements MouseListener'
eg
public class TestMouse extends Applet implements
MouseListner { etc.

I would now like to write an applet that uses both of these so that I can
detect the mouse actions as well as do some timing.

Could someone show me the structure that would be used to allow both
implements Runnable and MouseListener in the same Java applet? This is
probably quite obvious to a regular Java programmer but I am an old style
programmer trying to convert to Java.

Thank you.

Hi,
Although a class can only *extend* one other class, it can *implement*
any number of interfaces:

public class MyApplet extends Applet implements Runnable,
MouseListener {
....
}

Just keep adding more and more with commas until you have everything
you need.

The most typically, timing thread, which is your runnable, does some
sleep() and call applet's repaint() -- that is it is a controller for
some animation. MouseListener will do whatever it likes in its various
methods.

Thank you, Chris. That is the simply, easy-to-follow answers that are
great!!
