1. Difference between class and object:
i. Class is the template / blueprint of an object. Object is the instance of a class.
ii. Class describe the properties / method of an object. Object is a real world entity.
iii. From one class we can made unlimited objects.
iv. Class is constant but object is variable.
v. Class is a logical entity but object is a physical entity.
2. For example a human and its basic properties / behavior is the class, you and me is the object of the human class. If we go for an another example we can say that tiger, deer, elephant, dog etc are objects of animal class
