For example Cat and Dog are subtypes of type Animal. The designers of Java decided that checking at runtime whether a method existed was not a good ...

Benefit C++ templates have over Java and C# is that they allow for template metaprogramming which is a way of pre- evaluating some of the code at compile-time

property of the program text; static type has nothing to do with runtime We will then use the term dynamic type for the type of the value of an expression at runtime; dynamic type has nothing to do with compile-time The dynamic type of an expression can change as values are assigned to variables Animal Cat age( )

Java-07- 2 Introduction to Polymorphism There are three main programming mechanisms that constitute object-oriented programming (OOP) Encapsulation Inheritance Polymorphism Polymorphism is the ability to associate many meanings to one method name It does this through a special mechanism known as late binding or dynamic binding
Polymorphism-ad hoc polymorphism pure polymorphism method
There are two types of polymorphism in java: 1) Static Polymorphism also known as compile time polymorphism 2) Dynamic Polymorphism also known as runtime polymorphism Compile time Polymorphism (or Static polymorphism) Polymorphism that is resolved during compiler time is known as static polymorphism Method overloading is an example of compile
Polymorphism through the Java Interface - University of Arizona

The last line prints the value of c toString() Java uses the value of a the static type's field but the dynamic type's methods Variable c has dynamic type D because it refers to an object of type D So Java uses the toString method defined in class D which returns the values of x y and z within class D (or "DxAyDz")
Does Java support run-time polymorphism?
- Java supports run-time polymorphism by dynamically dispatching methods at run time through method overriding. For this type of polymorphism, method invocations are resolved at run time by the JVM and not at the compile time. Since the run-time polymorphism occurs dynamically, it is also called dynamic polymorphism or late binding.
What is the difference between compiler and run-time polymorphism?
- Differences Between Compile-time and Run-time Polymorphism Method overloading occurs at Compile-time whereas method overriding occurs at Run-time. Method overloading occurs when the type signatures of the two methods are different whereas method overriding occurs only when the type signatures of the two methods are the same.
What are the different types of compile-time polymorphism?
- There are two types of compile-time polymorphism. When different functions in a class have the same name but different signature, it’s called method overloading. A method signature contains the name and method arguments.
What is run time polymorphism?
- This is run time polymorphism. In this type of binding, the compiler adds code that identifies the object type at runtime then matches the call with the right function definition. This is achieved by using the virtual function. A virtual function is a member function of a base class which is redefined in the derived class.
