1.       0-Arg Constructor:-

If we declare any constructor without parameters then that constructor is called as 0-Arg constructor.

Note:-

All default constructor are 0-arg constructors, but, all 0-args constructors are not default constructers, some 0-args constructor which are provided compiler are called as default constructor and some other 0-arg constructor provided by the developers, these constructors, are called as user defined constructors.
