Object vs Class in Java

There are many differences between an object and a class:

Class is a template or a blueprint for object creation.The object is an instance of a class.
The class does not allocate any memory when created.The object is allocated memory when created.
The class is a logical entity.The object is a physical entity.
Class is declared using a class keyword.Object is created using new, forName ().newInstance () , clone() methods.
Class is a group of identical objects. E.g. Class Animals ().Object is a specific entity. E.g. Animals dog = new Animals ();
The class can be declared only once.A class can have any number of instances or objects.
A class member field doesn’t have any values.Every object has a copy of member fields and their associated values.
