JXAM Qs....

This is a Q from JXam.
Consider the following piece of code and select the correct statements.

1. Object o = new String("abcd");
2. String s = o;
3. System.out.println(s);
4. System.out.println(o);
A.
The following is displayed:
abcd
abcd

B.
The code fails to compile at line 1.
C.
The code fails to compile at line 2
D.
The code fails to compile at line 4.
E.
The code can be made to compile by changing line 1 to the following:
String o = new String("abcd");
The answer given is C. But I feel it should be C & E both.
Is it possible for the Inner Class to be the Sub class of the Outer Class ??

Yes. E should be correct too.
Yes. It is possible for the Inner Class to be the Sub class of the Outer Class. For. eg. the following code compiles fine...
class Outer
{
class Inner extends Outer
{
}
}
HTH,
Paul.

Hello sonkal,
I have just tried out the program that you have written and found that C and E are correct. I dont understand why the answer is only C. Any one to further clarify on the same if this is wrong. What to do in these cases..
