Hierarchical inheritance, which is generally a form of inheritance where one or more classes is derived from one parent class.Here, the class A is a base class which is called by both B and C subclasses. Base class A has more than one derived class.
class A
{
void DisplayA()
{
System.out.println("This is A");
}
}
class B extends A
{
void DisplayB()
{
System.out.println("This is B");
}
}
class C extends A
{
void DisplayC()
{
System.out.println("This is C");
}
}
public class MainClass
{
public static void main(String args[])
{
System.out.println("Calling for subclass C");
C c = new C();
c.DisplayA();
c.DisplayC();
System.out.println("Calling for subclass B");
B b = new B();
b.DisplayA();
b.DisplayB();
}
}
