Java Inheritance Example Why does the following code display "New A New B"? class A { public A() { System.out.println("New A"); } } class B extends A { public B() { System.out.println("New B"); } } class Program { public static void main(String[ ] args) { B obj = new...
Inheritance is one of the fundamental principles of Object-Oriented Programming (OOP) that allows one class (the child class or subclass) to inherit fields and methods from another class (the parent class or superclass). This promotes code reuse, modularity, and better maintainability. In this a...
Inheritance in Java sets the parameters of a new class to include at least all the parameters of its parent class. Find out why this differs from...

Structural design patterns provide different ways to create aClassstructure (for example, using inheritance and composition to create a largeObjectfrom smallObjects). 1. Adapter Pattern The adapter design pattern is one of the structural design patterns and is used so that two unrelated interfaces ca...
