Multilevel Inheritance Example
class Animal {
void eat() {
System.out.prntln(“The animal is eating…”);
}
}
class Dog extends Animal {
void bark() {
System.out.println(“The dog is barking…”);
}
}
class BabyDog extends Dog {
void weep(){
System.out.println(“The Baby Dog is weeping”);
}
}

public class TestInheritance3 {
public static void main(String[]args){

BabyDog D = new babyDog();

D.eat();
D.bark();
D.weep();
}
}

Hierarchical Inheritance Example

class Animal {

void eat() {
System.out.println(“The animal is eating”);
}
}
class Dog extends Animal {
void bark() {
System.out.println(“The Dog is barking”);
}
}
class Cat extends Animal {
void meow() {
System.out.println(“The Cat is Meowing”);
}

}
public class TestInheritance4 {
public static void main(String[]args){

Cat c = new Cat();
c.meow();
c.eat();
// c.bark(); will give an error.
}
}
