What is the difference between a class and an object of a class?
The difference is simple and conceptual. A class is a template for objects. An object is a member or an “instance” of a class. An object has a state in which all of its properties have values that you either explicitly define or that are defined by default settings.
Can object name be same as class name?

How do I find my class name?
The simplest way is to call the getClass() method that returns the class’s name or interface represented by an object that is not an array. We can also use getSimpleName() or getCanonicalName() , which returns the simple name (as in source code) and canonical name of the underlying class, respectively.
