Error when creating inner instance object...

Question

public class Outer{
          class Inner{}
          public static void main(String[] s){
           Outer o = new Outer();
           Outer.Inner i = o.new Outer.Inner();
           /*above is what my tutorial has taught me, but when a compile time         error?*/
}Can any spot the error of the above??

Answer 1

I'd say the error is in trying to do that in the first place.
What's the exact error you get when you try to compile?
As a guess, I'd say that Outer.inner isn't valid because Inner isn't static, just like Outer.foo() wouldn't be valid if you had a non-static method foo(). Just like you'd need to do o.foo(), you probably need to do o.inner.
Have I just done your homework for you?
