Creating a Multilevel Inheritance Hierarchy in Java
Inheritance involves an object acquiring the properties and behaviour of another object. So basically, using inheritance can extend the functionality of the class by creating a new class that builds on the previous class by inheriting it.
Multilevel inheritance is when a class inherits a class which inherits another class. An example of this is class C inherits class B and class B in turn inherits class A.
A program that demonstrates a multilevel inheritance hierarchy in Java is given as follows:
Example
class A {
void funcA() {
System.out.println("This is class A");
}
}
class B extends A {
void funcB() {
System.out.println("This is class B");
}
}
class C extends B {
void funcC() {
System.out.println("This is class C");
}
}
public class Demo {
public static void main(String args[]) {
C obj = new C();
obj.funcA();
obj.funcB();
obj.funcC();
}
}Output
This is class A This is class B This is class C
