Hybrid Inheritance

Derivation of a class involving more than one form of Inheritance is called Hybrid Inheritance.

Example:

import javax.swing.JOptionPane;

class Student

{

            int rno;

            String name;

            void readdata1()

            {

            rno=Integer.parseInt(JOptionPane.showInputDialog("Enter roll number"));

            name=JOptionPane.showInputDialog("Enter name");

            }

            void printdata1()

            {

            System.out.println("Roll number="+rno);

            System.out.println("Name       ="+name);

            }

}

class Test extends Student

{

            int m1,m2,m3;

            void readdata2()

            {

            m1=Integer.parseInt(JOptionPane.showInputDialog("Enter sub1 marks"));

            m2=Integer.parseInt(JOptionPane.showInputDialog("Enter sub2 marks"));

            m3=Integer.parseInt(JOptionPane.showInputDialog("Enter sub3 marks"));

            }

            void printdata2()

            {

            System.out.println("Sub1="+m1+"    Sub2="+m2+"    Sub3="+m3);

            }

}

interface Sports

{

            int smarks=55;

            public void printdata3();

}

class Result extends Test implements Sports

{

            int sum;

            public void printdata3()

            {

            System.out.println("Sports marks="+smarks);

            }

            public void readdata3()

            {

            readdata1();

            readdata2();

            }

            public void printdata4()

            {

            sum=m1+m2+m3+smarks;

            printdata1();

            printdata2();

            printdata3();

            System.out.println("Total Marks="+sum);

            }

}

class hy

{

            public static void main(String[] args)

            {

            Result obj=new Result();

            obj.readdata3();

            obj.printdata4();

            }

}
