   • Example of Runtime polymorphism in Java?

     Yes this is Runtime polymorphism in Java

     In static polymorphism, compiler itself determines which method should call. Method overloading is an example of static polymorphism.

     In runtime polymorphism, compiler cannot determine the method at compile time. Method overriding(as your example) is an example of runtime polymorphism. Because in Runtime polymorphism (as your example), the signature of methodA() is similar in both the class X(base class) and Y(child class). So compiler cannot determine method at compile time which should execute. Only after object creation(which is a run time process), the runtime environment understand the exact method to call.

     It is because of that in this case, obj1.methodA() calls methodA() in Class X since obj1 is reference variable of object created for class X

     AND obj2.methodA() calls methodA() in Class Y since obj2 is reference variable of object created for class Y

   • Java example featuring encapsulation, polymorphism, and inheritance?

     Top Answer

     Answered Jun 25, 2014 · 4 votes

     Your polymorphism example is merely method overloading and that's not actually what the Object Oriented folks mean by polymorphism. They mean how you can have a interface that exposes a method, and the various classes that implement that interface can implement the method to have different behaviors.

     See this. Last paragraph of the introduction in particular.

     Also, I would suggest that the best way to demonstrate knowledge of polymorhpism in code would necessarily include some client code that uses the polymorphic objects to demonstrate that they can have different, i.e. poly, behaviors.

   • Polymorphism in Python VS Polymorphism in JAVA

     Top Answer

     Answered Apr 10, 2020 · 0 votes

     The way I have always understood this:

     Polymorphism is a concept that basically says it looks like the same but does things differently, depending on context.

     • if you have a method of the same name which has a different amount of arguments, this is method overloading.
     • if you have a method of the same name with the same amount of arguments, but does a different thing depending on the class, this is method overriding.

     Note: I say amount of arguments, as for dynamically typed languages, the type does only matter at run time. For Java, for instance, it is not only the number of arguments, but also the type, of course.

     Both are concrete ways to deal with polymorphism. In detail, depending on the language you are using, the concept might be implemented and sometimes even interpreted differently.

   • Polymorphism in Java

     The word polymorphism means having many forms. In simple words, we can define Java Polymorphism as the ability of a message to be displayed in more than one form. In this article, we will learn what is polymorphism and it’s type.

     Real-life Illustration of Polymorphism in Java: A person at the same time can have different characteristics. Like a man at the same time is a father, a husband, and an employee. So the same person possesses different behaviors in different situations. This is called polymorphism. 

     What is Polymorphism in Java?

     Polymorphism is considered one of the important features of Object-Oriented Programming. Polymorphism allows us to perform a single action in different ways. In other words, polymorphism allows you to define one interface and have multiple implementations. The word “poly” means many and “morphs” means forms, So it means many forms.

     Types of Java Polymorphism

     In Java Polymorphism is mainly divided into two types: 

     • Compile-time Polymorphism
     • Runtime Polymorphism

     Compile-Time Polymorphism in Java

     It is also known as static polymorphism. This type of polymorphism is achieved by function overloading or operator overloading.

   Jan 4, 2023 · Polymorphism is the ability to create a variable, function, or object with more than one form. In java, polymorphism is divided into method overloading and method overriding. Another term, operator overloading, is also there. For example, the “+” operator can be used to add two integers as well as concat two sub-strings.

   • It will make our code inconsistent. To solve this, polymorphism in Java allows us to create a single method render () that will behave differently for different shapes. Note: The print () method is also an example of polymorphism. It is used to print values of different types like char, int, string, etc.
