Hi,
I am preparing for the SCJP but i fount is interesing while i observed some scenarios. I am curious about these things and want to get my doubts cleared.Here are the some observations i could make out.

1. What is the sigmificance of a regular inner class which is abstract or an interface.
2. If i have a inner class which is abstract or an interface what is its significance outside the class, For ex:

public class Test {
public abstract class Inner{
}
}
class Test1 extends Test{
Test.Inner ob = new Test().new Inner();
}
Can i instantiate the inner class somehow in Test1.If yes what will be the syntax.

Same rules apply as top level classes, you cannot instantiate abstract classes.

Yes, but you could make an anonymous class of the abstract class, e.g.
output is something like
Test$1@1f6a7b9

Then you have an anonymous inner class of an abstract inner class...

(I removed the public modifiers to have them all in one file)



Yours,
Bu.
 
Don't get me started about those stupid light bulbs.
