Polymorphism refers to the ability of an object to take on multiple forms. In Java, polymorphism occurs when a reference variable can refer to objects of different subclasses. This allows methods to behave differently depending on the actual object being referred to. There are three main forms of polymorphism in Java: method overriding, abstract method implementation, and interface implementation. Polymorphism provides benefits like simplicity and extensibility by allowing code to interact generically with base types and subclasses without needing specific type details.

Java abstract class & abstract methods,Abstract class in java
Abstract classes are classes that contain one or more abstract methods. An abstract method is a method that is declared, but contains no implementation. Abstract classes may not be instantiated, and require subclasses to provide implementations for the abstract methods.
Polymorphism is the ability of an object to take more than one forms. It is one of the important concept of object-oriented programming language. JAVA is object-oriented programming language which support the concept of polymorphisms.
Alternatively, it is defined as the ability of a reference variable to change behavior according to what object instance it is holding.

Learn Polymorphism in Python with Examples.pdfDatacademy.ai
In Python, polymorphisms refer to the occurrence of something in multiple forms. As part of polymorphism, a Python child class has methods with the same name as a parent class method. This is an essential part of programming. A single type of entity is used to represent a variety of types in different contexts (methods, operators, objects, etc.)

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

4. What is Polymorphism?
Generally, polymorphism refers to the ability to
●
appear in many forms
Polymorphism in a Java program
●
The ability of a reference variable to change
–
behavior according to what object instance it is
holding.
This allows multiple objects of different subclasses
–
to be treated as objects of a single super class,
while automatically selecting the proper methods to
apply to a particular object based on the subclass it
belongs to
4
5. Polymorphism Example
For example, given a base class shape,
●
polymorphism enables the programmer to define
different area methods for any number of derived
classes, such as circles, rectangles and triangles.
No matter what shape an object is, applying the
●
area method to it will return the correct results.
5
7. Example #1: Polymorphism
Given the parent class Person and the child class
●
Student, we add another subclass of Person
which is Employee.
Below is the class hierarchy
●
7
8. Example #1: Polymorphism
In Java, we can create a reference that is of type
●
super class, Person, to an object of its subclass,
Student.
public static main( String[] args ) {
Student studentObject = new Student();
Employee employeeObject = new Employee();
Person ref = studentObject; // Person reference points
// to a Student object
// Calling getName() of the Student object instance
String name = ref.getName();
}
8
9. Example #1: Polymorphism
Now suppose we have a getName method in our
●
super class Person, and we override this method in
both Student and Employee subclass's
public class Student {
public String getName(){
System.out.println(“Student Name:” + name);
return name;
}
}
public class Employee {
public String getName(){
System.out.println(“Employee Name:” + name);
return name;
}
9
}
10. Example #1: Polymorphism
Going back to our main method, when we try to call
●
the getName method of the reference Person ref,
the getName method of the Student object will be
called.
Now, if we assign ref to an Employee object, the
●
getName method of Employee will be called.
10
11. Example #1: Polymorphism
1 public static main( String[] args ) {
2
3 Student studentObject = new Student();
4 Employee employeeObject = new Employee();
5
6 Person ref = studentObject; //Person ref. points to a
7 // Student object
8
9 // getName() method of Student class is called
10 String temp= ref.getName();
11 System.out.println( temp );
12
13 ref = employeeObject; //Person ref. points to an
14 // Employee object
15
16 //getName() method of Employee class is called
17 String temp = ref.getName();
18 System.out.println( temp );
19 }
11
12. Example #2: Polymorphism
Another example that illustrates polymorphism is
●
when we try to pass a reference to methods as a
parameter
Suppose we have a static method printInformation
●
that takes in a Person reference as parameter.
public static printInformation( Person p ){
// It will call getName() method of the
// actual object instance that is passed
p.getName();
}
12
13. Example #2: Polymorphism
We can actually pass a reference of type Employee
●
and type Student to the printInformation method as
long as it is a subclass of the Person class.
public static main( String[] args ){
Student studentObject = new Student();
Employee employeeObject = new Employee();
printInformation( studentObject );
printInformation( employeeObject );
}
13
15. Benefits of Polymorphism
Simplicity
●
If you need to write code that deals with a family of types,
–
the code can ignore type-specific details and just interact
with the base type of the family
Even though the code thinks it is using an object of the
–
base class, the object's class could actually be the base
class or any one of its subclasses
This makes your code easier for you to write and easier
–
for others to understand
15
16. Benefits of Polymorphism
Extensibility
●
Other subclasses could be added later to the family of
–
types, and objects of those new subclasses would also
work with the existing code
16
18. 3 Forms of Polymorphism
in Java program
Method overriding
●
Methods of a subclass override the methods of a
–
superclass
Method overriding (implementation) of the abstract
●
methods
Methods of a subclass implement the abstract methods
–
of an abstract class
Method overriding (implementation) through the
●
Java interface
Methods of a concrete class implement the methods of
–
the interface
