Multiple Inheritance

Multiple Inheritances does not support by Java directly.  Multiple Inheritances enables to derive a class from multiple parent classes.

Let A and B are parent classes and C is the derived class

            Java provides Interface approach to support the concept of Multiple Inheritance.  A class can also implements multiple interfaces.

Example:

class Test

{

            int sub1,sub2,sub3;

            void readdata1(int x,int y,int z)

            {

            sub1=x;

            sub2=y;

            sub3=z;

            }

            void printdata1()

            {

            System.out.println("sub1 marks="+sub1);

            System.out.println("sub2 marks="+sub2);

            System.out.println("sub3 marks="+sub3);

           

            }

}

interface Sports

{

            int smarks=55;

            public void printdata2();

}

class Result extends Test implements Sports

{

            int sum;

            public void printdata2()

            {

            printdata1();

            sum=sub1+sub2+sub3+smarks;

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

            }

}

class mul

{

            public static void main(String[] args)

            {

            Result obj=new Result();

            obj.readdata1(35,67,89);

            obj.printdata2();

            }

}
