Question

Discuss about Hybrid inheritance with an example.

Answer 1

Hybrid Inheritance is a combination of both  Single Inheritance and Multiple Inheritance.  Since in java Multiple Inheritance is not supported directly we can achieve Hybrid inheritance also through Interfaces only. 

Implementation of Hybrid Inheritance

public class ClassA
{
public void dispA()
{
System.out.println("disp() method of ClassA");
}
}
public class ClassB extends ClassA
{
public void show() {
System.out.println("show() method of ClassB");
}
public void dispB()
{
System.out.println("disp() method of ClassB");
}
}
public class ClassC extends ClassA
{
public void show()
{
System.out.println("show() method of ClassC");
}
public void dispC()
{
System.out.println("disp() method of ClassC");
}
}
public class ClassD extends ClassB,ClassC {
public void dispD() {
System.out.println("disp() method of ClassD");
}
public static void main(String args[])
{
ClassD d = new ClassD();
d.dispD();
d.show();//Confusion happens here which show method to call
}
}

Output :

Error!!

Hope it helps you!!!
