can anyone tell me why if we want a different implementation of a method of parent class in sub class,why don't we write a new method with a new name than create a method that has same name as method of parent class but has different code. what is advantage of overriding over creatin...
Overriding and overloading are the core concepts in Java programming. They are the ways to implement polymorphism in our Java programs. Polymorphism is one of the OOPS Concepts. Screenshot of Java code with arrows pointing at instances where overloading and overriding are occurring. When the met...
