constructor is used for initializing the class
variables.if constructor is not there,variables might be
taken the garbage values.To avoid garbage
values ,constructor is used.

Answer / sekhar

Constructor is like a method.It can be invoked as soon as
we create an object for the class.We can overload
constructor.to call them we need pass parameters in main
method.

Answer / ejp

A constructor isn't required so the question is futile. Both
answers above are wrong.

Specifically, in reply #1, 'if constructor is not
there,variables might be taken the garbage values' is itself
complete garbage.

Reply #2, is mostly irrelevant, but this statement 'to call
them we need pass parameters in main method' is also wrong.
Parameters are not required, and the reference to the main
method is pointless.
