It is an example of compile-time polymorphism. In the below example, A function ADD is used to perform two tasks. Method overriding is an example of runtime polymorphism.
In method overriding, a subclass overrides a method with the same signature as that of in its superclass. During compile time, the check is made on the reference type. The compile time polymorphism can be achieved by function overloading or by operator overloading.
Compile-time polymorphism: We can achieve this type of polymorphism only during compilation. Q Which feature comes under compile time polymorphism? Method overloading, and constructor overloading come under compile time polymorphism. Compile time polymorphism is achieved by method overloading and operator overloading in C. It is also known as static binding or early binding. Runtime polymorphism in achieved by method overriding which is also known as dynamic binding or late binding.

This transfer of implementation of one method to another method is possible without changing or modifying the codes of the parent class object.
Compile-time and Runtime are the two programming terms used in the software development. Compile-time is the time at which the source code is converted into an executable code while the run time is the time at which the executable code is started running. The word polymorphism means having many forms. Real life example of polymorphism: A person at the same time can have different characteristic.
Like a man at the same time is a father, a husband, an employee. So the same person posses different behavior in different situations. In a real scenario, an end user will not be aware of the implementation class. Hence, an object of the implementation class can be provided by the factory method. Factory method can be used to create an object of implementation class based on some criterion. There are two types of polymorphism one is Compile-time polymorphism and another is run-time polymorphism.
Method overloading is the example of compile time polymorphism and method overriding is the example of run-time polymorphism. Polymorphism is the ability of an object to take on many forms. Any Java object that can pass more than one IS-A test is considered to be polymorphic— tutorialspoint. This means any child class object can take any form of a class in its parent hierarchy and of course itself as well.
All the types of blood groups are the example of genetic polymorphism, such as the ABO blood group system. We see this system having more than two morphs: A, B, AB, and O are the variants present in the entire human population, but these groups vary in proportion in different parts of the world. Inheritance in Java is a concept that acquires the properties from one class to other classes; for example, the relationship between father and son.
In Java, a class can inherit attributes and methods from another class. The class that inherits the properties is known as the sub-class or the child class. Which type of function among the following shows polymorphism? Explanation: Only virtual functions among these can show polymorphism.
The main advantage of this is cleanliness of code. Method overloading increases the readability of the program. Overloaded methods give programmers the flexibility to call a similar method for different types of data.
