java-programmer, How do i implement this interface public interface AQuestion
{
public abstract void someMethod() throws Exception;
}




http://www.angelfire.com/or/abhilash/Main.html

see Question no 5.


How do i implement this interface ?

(1) problem is, it has an abstract method and hecne its complicated
to implement this class.

(2) another problem is, it is the public interface and hence we can not
make one more public class in the same file....because 1 file can have
only 1 public access specifier.




is it really possible to implement this interface ?

All interface methods are automatically public and abstract, so the
modifiers are redundant. This interface is exactly the same as:

public interface AQuestion
{
void someMethod() throws Exception;
}

So put it in another file.

Yes.
