1) Compilation error due to malformed parameter to go method
2) Compilation error, class Turing has no start method
3) Compilation and output of 0 followed by 1
4) Compilation but runtime error



Could any one suggest the answer for this? My answer is 2, because passing an instance of newly created anonymus inner class will override the existing class.

What do you say?

i think answer is 3, since in this case of anonymous class, the annonymous class automatically extends the turing class and hence inherit the go method as well as other methods of it's parent class.

Why don't we try it to compile and run?

output:


Turing inherits start from Thread, once declared as public, it is part of Thread's interface and every instance of Thread or its sub-classes can call it. You can't make it more private or hide it.

A method local is a class defined inside the method like:


Original post is an example of Anonymous class; inside the method go()
you are passing and instance of Anonymous class that subclasses the
class Turning.
