25. Assume that there are two packages, student and exam. A student package contains
Student class and the exam package contains Result class. Write a program that generates
mark sheet for students.
// Scanner.nextInt method does not read the newline character in your input created by hitting "Enter,"
and so the call to Scanner.nextLine returns after reading that newline.

26. Define a class A in package apack. In class A, three variables are defined of access
modifiers protected, private and public. Define class B in package bpack which extends A and
write display method which accesses variables of class A.
Define class C in package cpack which has one method display() in that create one object of class
A and display its variables. Define class ProtectedDemo in package dpack in which write main ()
method. Create objects of class B and C and class display method for both these objects.
