MULTIPLE INHERITANCE

Exno:                                       MULTIPLE INHERITANCE

Aim:

To write a java program to implement the concept of multiple inheritance.

Algorithm:

Step1: Start.

Step2: Define a class stu to get the name and roll no and display the same.

Step3: Define a class test that acts as a sub-class of stu. Get the marks m1, m2 and display the same.

Step4: Define an interface sports that carries the spors weightage.

Step5: Define class  result that extends class test and implements interface sports.

Step6: Calculate the total marks in class result.

Step7: Define class final pgm and void main() as public static.

Step8: Declare an object ‘s’ to class result and invoke getdata(), getmark() and display() to print the output.

Step9: Stop.

Program:

class stu

{

String name;

int rollno;

void getdata(String s,int r)

{

name=s;

rollno=r;

}

void putdata()

{

System.out.println("\nName="+name);

System.out.println("\nRoll No="+rollno);

}

}

class test extends stu

{

int m1,m2;

void getmarks(int x,int y)

{

m1=x;

m2=y;

}

void putmarks()

{

System.out.println("\nMark1="+m1);

System.out.println("\nMark2="+m2);

}

}

interface sports

{

final int sp=6;

abstract void putsp();

}

class result extends test implements sports

{

int tot;

public void putsp()

{

System.out.println("\nSports wt="+sp);

}

void display()

{

tot=m1+m2+sp;

putdata();

putmarks();

putsp();

System.out.println("\nTotal="+tot);

}

}

class ex2

{

public static void main(String args[])

{

result s=new result();

s.getdata("Anitha",101);

s.getmarks(98,99);

s.display();

}

}

OUTPUT:

Z:\anitha>javac ex2.java

Z:\anitha>java ex2

Name=Anitha

Roll No=101

Mark1=98

Mark2=99

Sports wt=6

Total=197
