Only if the class has no constants and references ( have to initialized upon creation)

also when you create a consturctor with arguments, it has to call defaul no argument consturctor :).

If the class designer has not provided any constructor within the class, but we are trying to create an object of that class without passing any argument , then compiler will provide a default zero argument constructor. But in the same scenario, if we are creating an object and trying to pass argument(s) to the object at the time of its creation, in that case compiler will not provide any  one-argument, two-argument constructors etc. It will throw an error.
