how to use javadoc

[krishanu]

Hi,
I have a very small program....bellow is the code

class AbstractDemo {
public static void main(String args[])
{
B b = new B();
b.callme();
b.callmetoo();
}
}
abstract class A
{
abstract void callme();
void callmetoo()
{
System.out.println("This is concrete method");
}
}

class B extends A
{
void callme()
{
System.out.println("B's implementation callme");
}
}

Now question is how to create documentation for this program.
I can specify only a single source file ..
javadoc override.java

but its giving me the error ..."No public or private class found to document"

I am very new to java....so can anybody please tell me how to use this javadoc feature??

any help is appreciated!!!!

Well, that class probably ought to be public.

public class AbstractDemo  {...}
