How to close java Applet through code

I am developing a java applet. I want it to be closed by the code. I have used System.Exit(0) but it is not working. Is there any other method to achieve this?

Thanks

As said above,exiting applet is simple by adding System.exit(0) in if(condition) for which you want to close the applet.Though I am describing of applet viewer.But,it certainly works fine.

Try to remove java applet code by javascript. Example your html:

<button onclick="clickButton()">Click me</button>
<div id="appletCode">
     <applet width="200" height="200" archive="ImageIconApplet.jar"
        code="com.whitefang34.ImageIconApplet" name="test"/> 
</div>

your javascript code:

function clickButton(){
     var SS = document.getElementById("appletCode");
    SS.innerHTML = "";
}

applet.getAppletContext().showDocument("ThanksForUsingOurApplet.html");

As to the comment that a signed applet can call System.exit(n).

It can in some browser/JRE combos., it can't in others. In the ones that it can, it shouldn't since an applet may share a VM with other applets (less common these days), and even if not, it is the user's responsibility to close an applet by closing the page.

An applet is a guest in a web page. Calling System.exit(n) is like burning down the guest house.

An applet cannot call System.exit(int);. Security permissions don't let an applet do this. And if you are trying to close the browser window, even if you signed the code and the browser/user trusted you, the browser wouldn't let you shutdown/close the browser window.

If all you want to do is close a Window/Frame created from the applet, this is no different than closing a window outside of an applet.
