Although , it is clearly mention in K&B that , this type of error depends on type of compiler . But suppose this come in exam & options are :
1] compile time error .
2] run time error .

then what shuould be the answer .

thanks .

The compiler can detect these kind of recrusive calls. So I would select Compile error.

My compiler detected recursive calls, too.
However, this was compiled and ran until reaching StackOverflowError:
Why are constructors a special case then?
Obviously, a method can call itself (to implement recursion). So, are two methods allowed to call each other recursively for the same reason?
Or is it just too much of a hustle for compiler to track recursive calls (especially in case of more than two methods)?
Thanks

A recursive method call should have some terminating condition. If a programmer fails to provide that terminating condition, then that is his error and will result in a stack overflow.

A constructor, however, does not normally have a terminating condition, although I suppose you can simulate one by throwing an exception. Also, since a constructor does not have a retrun value, I don't know why a program would ever need to call a constructor recursively.
 
I agree. Here's the link: http://aspose.com/file-tools
