Problem 3

CODE:

import java.util.Scanner;
 
interface Sports {
    void putSportsScore(int s);
}
 
class Student {
    int roll;
    int marks;
 
    void getRollNum(int r) {
        roll = r;
    }
 
    void putRollNum() {
        System.out.println("Roll No: " + roll);
    }
 
    void getMarks(int m) {
        marks = m;
    }
 
    void putMarks() {
        System.out.println("Marks: " + marks);
    }
}
 
class Result extends Student implements Sports {
    int sportsScore;
 
    public void putSportsScore(int s) {
        sportsScore = s;
    }
 
    void showResult() {
        putRollNum();
        putMarks();
        System.out.println("Sports Score: " + sportsScore);
        System.out.println("Total Score: " + (marks + sportsScore));
    }
}
 
public class ProblemThree {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        Result r = new Result();
 
        System.out.print("Enter Roll No: ");
        r.getRollNum(sc.nextInt());
 
        System.out.print("Enter Marks: ");
        r.getMarks(sc.nextInt());
 
        System.out.print("Enter Sports Score: ");
        r.putSportsScore(sc.nextInt());
 
        r.showResult();
    }
}

OUTPUT:

Enter Roll No: 51
Enter Marks: 96
Enter Sports Score: 88
