Constructor is public method which is called automatically when object of class is created. It is created when you want to initilize class members of the class.Constructor of class is called single time in life cycle of the object.Constructor in static class can also be created and this is called "Private / Staic " constructor. We can not create object of static class because of that this constructor is called only single time when first time class name is used to use any member of same class. Every class has defult zero argument constuctor, but when we use constructor overloading then we have to write zero argument constrouctor too. Source: CoolInterview.com

=>Instance Constructor:It will be called automatically when the object is created
