Hello Everybody,
I'm just started Java thru complete reference, i would like to know whether can we have both main() and init() function in a class, and that class should be extended by what class?

You can have both main() and init()functions in a class. You need <pre>
public class myClass{
public static void main(){
...
}
}
</pre>
for any application to begin; init() is optional and is called only if you call it.
If you build an applet,
<pre>
public class myClass extends java.applet.Applet{
...
}
</pre>
you need to write and init() method to override the init() method provided by java.applet.Applet to initialize your class; main() is optional and is called only if you call it.

Okay Marylin...as far as being legal or not legal is concerned , you have clearified it..but can you please explain a little more..having a static main method in the code wouldn't it be a problem if we write an applet that has init method(mendatory).
Thanks...

It shouldn't be a problem. If you run an applet, main() would just never be called. Alternatively, you could just put a call to main() in your init() method and initialize everything inside main().
