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.
