Write a JAVA program illustrating multiple inheritance using interfaces.

import java.lang.*;
import java.io.*;
interface Exam
{
void percent_cal();
}
class Student
{
String name;
int roll_no,mark1,mark2;
Student(String n, int r, int m1, int m2)
{
name=n;
roll_no=r;
mark1=m1;
mark2=m2;
}
void display()
{
System.out.println ("Name of Student: "+name);
System.out.println ("Roll No. of Student: "+roll_no);
System.out.println ("Marks of Subject 1: "+mark1);
System.out.println ("Marks of Subject 2: "+mark2);
}
}
class Result extends Student implements Exam
{
Result(String n, int r, int m1, int m2)
{
super(n,r,m1,m2);
}
public void percent_cal()
{
int total=(mark1+mark2);
float percent=total*100/200;
System.out.println ("Percentage: "+percent+"%");
}
void display()
{
super.display();
}
}
class MultipleInheritance
{
public static void main(String args[])
{
Result R1 = new Result("hasini",12,93,84);
R1.display();
R1.percent_cal();
Result R2 = new Result("diya",15,90,75);
R2.display();
R2.percent_cal();
}
}

Output:
