Answer 1

Program Code

import java.io.*; import java.util.*; class Student {    Scanner sc=new Scanner(System.in);    int RegNo,Total=0,subjects;    String name;    int marks[];    Student()    {       System.out.print("Enter Registration No.: ");       RegNo=sc.nextInt();       System.out.print("Enter Student Name: ");       name=sc.next();;       getDisMarks();    }    public void getDisMarks()    {        marks=new int[3];        System.out.print("Enter marks of Physics: ");        marks[0]=sc.nextInt();        System.out.print("Enter marks of Chemistry: ");        marks[1]=sc.nextInt();        System.out.print("Enter marks of Maths: ");        marks[2]=sc.nextInt();        for(int i=0;i<3;i++)        {           Total+=marks[i];        }        System.out.println("Total Marks of student "+name+": " +Total);    } } class StudentDemo {     public static void main(String args[])     {         Student s[]=new Student[5];         for(int i=0;i<5;i++)               s[i]=new Student();      } }

Output

Enter Registration No.: 624 Enter Student Name: Ankit Enter marks of Physics: 95 Enter marks of Chemistry: 94 Enter marks of Maths: 95 Total Marks of student Ankit: 284 Enter Registration No.: 527 Enter Student Name: Aditya Enter marks of Physics: 97 Enter marks of Chemistry: 93 Enter marks of Maths: 89 Total Marks of student Aditya: 279 Enter Registration No.: 093 Enter Student Name: Namrata Enter marks of Physics: 85 Enter marks of Chemistry: 90 Enter marks of Maths: 95 Total Marks of student Namrata: 270 Enter Registration No.: 123 Enter Student Name: Unknown Enter marks of Physics: 69 Enter marks of Chemistry: 79 Enter marks of Maths: 89 Total Marks of student Unknown: 237 Enter Registration No.: 789 Enter Student Name: Known Enter marks of Physics: 75 Enter marks of Chemistry: 65 Enter marks of Maths: 24 Total Marks of student Known: 164
