// Concrete class 2
class Cat extends Animal {
// Implementing abstract methods

@Override
public void makeSound() {
System.out.println(“Meow!”);
}

@Override
public void eat() {
System.out.println(“Cat is eating”);
}

}

// Main class
public class AnimalExample {
public static void main(String[] args) {

// Create instances of concrete classes
Dog myDog = new Dog();
Cat myCat = new Cat();

// Call abstract and concrete methods

myDog.makeSound();
myDog.eat();
myDog.sleep();

myCat.makeSound();
myCat.eat();
myCat.sleep();
}
}
Explanation:

1. Abstract Class (Animal):
• Declares two abstract methods makeSound() and eat().
• Defines a concrete method sleep() with a default implementation.
2. Concrete Classes (Dog and Cat):

• Extend the abstract class Animal.
• Provide implementations for the abstract methods makeSound() and eat().
