the program outputs “The dog barks” and “The cat meows”. Even though the variables are declared as Animal, the actual behavior is determined by the specific subclass instance that they hold. This is the power of polymorphism in Java, allowing us to write more flexible and reusable code.
since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better understandi...
In this possible approach, we are going to apply the con_str method to demonstrate the working of compile time polymorphism by changing the number of parameters. String con_str = s1 + s2; System.out.println("Concatenated strings :"+ con_str); Example Open Compiler //Java program to demo...
In Java,Polymorphismenables us to process objects of the samesuperclassas if they are objects of thesuperclass.Subclassesof thesuperclasscan define their own unique behaviors and yet share some of the same functionality of thesuperclass. To demonstrate polymorphic features in the Java language, let...
Polymorphism—or an object’s ability to execute specialized actions based on its type—is what makes Java code flexible. Many design patterns created by theGang Of Fourrely on some form of polymorphism, including theCommand pattern. In this article, you will learn the basics of Java polymorphis...

Examples of polymorphism in JavaAt Execution Time
Polymorphism enables the writing of methods that can constitute different types of entities bearing the same name.Polymorphism is essential in Java because of its various usage benefits and the scope it provides for making the code dynamic:
In the last tutorial we discussed Polymorphism in Java. In this guide we will see types of polymorphism. There are two types of polymorphism in java: 1) Static Polymorphism also known as compile time polymorphism 2) Dynamic Polymorphism also known as run
