With static polymorphism, the compiler determines which method should be called. Method overloading is an example of noise polymorphism. At runtime, polymorphism, which is the compiler, cannot determine the method at collection time. Method substitution (as in your good example) is an example of learning polymorphism.
Polymorphism in Java is an optionme, which allows us to use the correct single in different ways. Polymorphism comes from two Greek texts: poly and morphs. “Poly” means “many” and means “transformed” forms. So polymorphism means multiple forms.
Java will definitely have two types of polymorphism: compile-time polymorphism and run-time polymorphism. We can perform polymorphism on Java systems by overloading and overriding methods.
If the public overload is a static method in Java, this is an example of fun compilation polymorphism. Here we will focus on runtime polymorphism in Java.
Java Runtime Polymorphism
What is runtime polymorphism in C++ with examples?
Runtime Polymorphism: This type of polymorphism is undoubtedly obtained through function substitution. On the other hand, function replacement occurs when you are a derived class that has an interpretation for one of the member parts of the base class. This Foundation function should simply be overwritten. // C ++ program to rewrite.
Runtime polymorphism, or dynamic method propagation, is a process in which invocation of a rewritten application is also resolved at runtime rather than at compile time.
In this case, the overwritten mode is invoked by reference to the superclass variant. The determination of which method to call is always based on the object into which the reference variable is being introduced.
If any referenced variable of the parent school refers to an object of the child class, this is known as an upward conversion. For example:
For better quality, we can use a custom class reference variable or some type of interface. For example:
From an object. is the root class of all classes in Java, we can all write an IS-A B object.

In this example, we are creating two classes Bike and Splendor. Splendor extends the Bike class and overwrites its run () product. We call the execution mode of the variable by reference of the parent class. Because it applies to most changes to the subclass object and subclass method to the parent class method, this particular subclass method is called at runtime.
Since the course invocation is defined by the JVM and not the compiler, it is almost called runtime polymorphism.
Java-it Runtime Polymorphism Example: Bank
Imagine a scenario where a bank -it is a class that provides a method to get the interest rate. However, commission rates may differ depending on the bank. For SBI, for example, the economic institutions ICICI and AXIS provide interest rates of 8.4%, 7.3% plus 9.7%.
Note: This example is probably also given when overwriting methods, even if there was no upconversion.

Java Runtime Polymorphism With Item
Method A is overloaded, but council members are not, so runtime polymorphism cannot always be achieved with data members.
In the image below, both classes have a data member rate limit. Item access is the process of going through a parent class reference variable that refers specifically to the subclass object. Since we are accessing data that has not been overwritten, we always callwe go to the data of the parent class.
Rule: Runtime polymorphism cannot be achieved by any piece of data. This

Which is runtime polymorphism?
Runtime polymorphism: whenever a part is connected to a function at runtime, we talk about runtime polymorphism. Execution polymorphism is probably achieved by overriding the method. The JVM determines the correct route to call at runtime, possibly at compile time.
Since BabyDog does not override the eat () style, the eat () method of the Dog classes is called.

Method substitution is an example of runtime polymorphism. When the structure is overwritten, the subclass overwrites the method based on the same signature as its superclass. At compile time, a specific type of test is checked over a period of time.However, in teachings the JVM will discover the object and also the type will execute the method that is often associated with that particular object.
