Method overriding is the process of redefining a superclass function in a subclass with the same method signature. The methods must have the same name, the same number of arguments, and the same kind of parameters in the same order if they have the same signature. It's used to modify ...
child class’s implementation is used. Modern programming languages like Java, Eifell, C++ and Python allows method overriding. What is Overloading? Method overloading is a feature provided by some programming languages to create more than one method with the same name, but with different input...
