Some Important difference between class and object

• Object is an instance of a class. Class is a blueprint or template from which objects are created.
• Object is a real world entity such as pen, laptop, mobile, bed, keyboard, mouse, chair etc. Class is a group of similar objects.
• Object is created many times as per requirement. Class is declared once.
• Object allocates memory when it is created. Class doesn't allocated memory when it is created.
• Object is a physical entity. Class is a logical entity.

Object is created through new keyword mainly e.g.

 Class is declared using class keyword e.g.

class Student{}
