Java program to show the use of methods in order to implement modularity

This program is implemented and  by Manoj Gupta from NIT Uttrakhand

import java.util.Scanner;

public class Student {

        // lets have some non static data members
 int roll;
 String name;
 String email;
 int hindi;
 int english;
 int physics;
 int chemistry;
 int maths;

 // a non static method to take input for data members
 void input_details()
 {
  //scanner object is created
  Scanner sc=new Scanner(System.in);

  //data entry is being done
  System.out.println("\n Enter your name ");
  name=sc.next();
  System.out.println("\n Enter your roll number ");
  roll=sc.nextInt();
  System.out.println("\n Enter your email address ");
  email=sc.next();
  System.out.println("\n Enter your marks in hindi ");

  System.out.println("\n Enter your marks in english ");
