Everything in Java is associated with classes and objects, along with its attributes and methods. For example: in real life, a car is an object . The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a “blueprint” for creating objects.

A Java object is a member (also called an instance) of a Java class . Each object has an identity, a behavior and a state. The state of an object is stored in fields (variables), while methods (functions) display the object’s behavior. Objects are created at runtime from templates, which are also known as classes.9 Eyl 2021

Read moreWhy is it called dynamic polymorphism?
speak() is same because according to compiler both methods are called on Mammal reference but the output for both method calls is different because at runtime JVM knows what object a reference is holding and JVM calls the method on the object and this is why Method Overriding is known as Dynamic Polymorphism.26 Ara 2013
