Write a Java Program to implement the concept of multiple inheritance using Interfaces

Source Code 

import java.util.Scanner;

//Student Detail

interface Detail

{

final String academic_year="2023-2024";

    public void getDetail();

}

//Student Marks 

interface Marks

{

public void getMarks();

    public void print();

}

//multiple inheritance using inteface

class Student implements Detail,Marks

{   

String rollno,name,degree,sem;

    int m1,m2,m3,total;

    float percent;

public void getDetail()

{

        Scanner in = new Scanner(System.in);

        System.out.print("Enter Student Roll Number : ");

        rollno = in.nextLine();

        System.out.print("Enter Student Name : ");

        name = in.nextLine();

        System.out.print("Enter degree : ");

        degree = in.nextLine();

        m2 = in.nextInt();

        System.out.print("Enter Mark3 : ");

        m3 = in.nextInt();

        total=m1+m2+m3;

        percent=(total*100)/300;

    }
