Question

Sure, here's an example of a program that demonstrates inheritance in J#: import system.*; // Base class class Animal { protected String species; public Animal(String species) { this.species = species; } public void eat() { Console.WriteLine("The " + species + " is eating."); } public void sleep() { Console.WriteLine("The " + species + " is sleeping."); } } // Derived class class Dog extends Animal { public Dog() { super("Dog"); } public void bark() { Console.WriteLine("The dog is barking."); } } // Main class class Program { public static void main(String[] args) { Dog dog = new Dog(); dog.eat(); // Inherited from Animal class dog.sleep(); // Inherited from Animal class dog.bark(); // Defined in Dog class } } Explanation: In this program, we have a base class called `Animal` that has two methods, `eat()` and `sleep()`, and a protected variable `species`. The `Animal` class serves as the parent class. We also have a derived class called `Dog` that extends the `Animal` class. The `Dog` class inherits the methods and variables from the `Animal` class and adds a new method called `bark()`. The `Dog` class serves as the child class. In the `main()` method of the `Program` class, we create an instance of the `Dog` class called `dog`. We can then call the inherited methods `eat()` and `sleep()` from the `Animal` class using the `dog` object. Finally, we call the `bark()` method defined in the `Dog` class. This demonstrates the concept of inheritance in J#. The child class (`Dog`) inherits the properties and behaviors of the parent class (`Animal`) and can also add its own unique properties and behaviors.
