Method over-riding : it is a technique in which more then one function with same name and same signature( similar type parameter) can present in program. in overriding a subclass method overrides the definition of base class method code and output mentioned in screenshot

This allows same function name to be made to behave according to child class or sub class needs. Virtual functions are best example for this.

first i will explain in a easy way about the overridding to change the functionality of a particular method in every child class compare to the parent class for example.. you want to prepare a biryani.. in parent class(Home,House) their a simple casual method to prepare biryani but in every child class(different restaurants) means in every restaurant they follow their own methodology compare to home recipe means parent class.. code in java for method overridig.. public class BiryaniH { public void prepare() { System.out.println("biryani is ready"); } } public class RestaurantOne extends BiryaniH { public void prepare() { System.out.println("biryani is ready at R1"); } } public class RestaurantTwo extends BiryaniH { void public void prepare() { System.out.println("biryani is ready at R2"); } } public class TestBiryni { public static void main(String args[]) { RestaurantOne obj1 = new RestaurantOne(); obj1.prepare(); RestaurantTwo obj2 = new RestaurantTwo(); obj2.prepare(); } } read less

Dear Sayyad, Never understand the classes in terms of Child and Parent, Consider them as extensions, like for example, Suppose you have a basic class (which provides some functionality via methods), which everybody is free to use, now imagine if somebody wants to provide own version of one of the methods, what are the options available. #1 Change the method in base class, which u have implemented. (Bad idea, because it will break the existing code). #2 Don't touch the class, which is in use and working, Derive a new class, and provide a new definition to the method, which u want to do differently. (Good idea, it'll not break anything), A real world example would be ... class Account { public : bool Deposit(Double amount); } class SavingAccount : public Account { public : bool Deposit(Double amount); } class CurrentAccount : public Account { public : bool Deposit(Double amount); } Do not try to copy paste and compile, this is just a pseudo-code. The explanation can continue, and we can take many more examples, where Method Overriding is used in real world. read less
