-

Question 4.

Define a class named BookFair with the following description:
Instance variables/Data members:
String Bname       –           stores the name of the book.
double price      –           stores the price of the book.
Member Methods:
(i)         BookFair()              Default constructor to initialize data members.
(ii)        void Input()               To input and store the name and the price of the book.
(iii)       void calculate()              To calculate the price after discount. Discount is calculated based on the following criteria.
PriceDiscount
Less than or equal to Rs 10002% of price
More than Rs 1000 and less than or equal to Rs 300010% of price
More than Rs 300015% of price
(iv)       void display()              To display the name and price of the book after discount.
Write a main method to create an object of the class and call the above member methods.

SOURCE CODE


import java.io.*;
import java.util.*;
class BookFair
{
    String Bname;
    double price,total;
    BookFair()
    {
        Bname="";
        price=0.0;
    }

    void Input()
    {
        Scanner sc=new Scanner(System.in);
        System.out.print("Enter name of book  :");
        Bname=sc.nextLine();
        System.out.print("Enter Price of book :");
        price=sc.nextDouble();        
    }

    void calculate()
    {
        double dis=0;
        if(price<=1000)
            dis=price*0.02;
        else if(price>1000&&price<=3000)
            dis=price*0.1;
        else if(price>3000)
            dis=price*0.15;
        total=price-dis;    
    }

    void display()
    {
        System.out.println("Name of Book    :"+Bname);
        System.out.println("Price of Book   :"+price);
        System.out.println("Price after of book discount    :"+total);
    }

    public static void main(String args[])
    {
        BookFair obj=new BookFair();
        obj.Input();
        obj.calculate();
        obj.display();
    }
}           

OUTPUT

[Question 3] ISC 2017 Computer Practical Paper Solved – Caesar Cipher.

Question 3: Caesar Cipher  is an encryption technique which is implemented as ROT13 (‘rotate by 13 places’). It is a simple letter substitution cipher that replaces a letter with the letter 13 places after it in the alphabets, with the other characters remaining unchanged. Write a program to accept a plain text of length L, where L must be greater than 3 and less than 100. Encrypt the text if valid as per the Caesar Cipher. Test your program with the sample data and some random data: Example 1 INPUT :  Hello! How are you? OUTPUT :  The cipher text is: Uryyb? Ubj ner lbh? Example 2 INPUT :  Encryption helps to secure data. OUTPUT :  The cipher text is: Rapelcgvba urycf gb frpher qngn. Example 3 INPUT :  You OUTPUT :  INVALID LENGTH SOURCE CODE    import java.io.*; import java.util.*; public class ISC2017_CaesarCipher {     public static void main(String args[])     {         Scanner sc=new Scanner(System.in);         System.out.pri

Pattern of your own name.

Pattern program of your own name. This is a pattern program, in this program you just have to enter your name and it will give you output in a particular manner. I have created this program when I was in class 10th for my Computer Application project. NOTE:  If you are copying my code then its a advise to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of source code. SOURCE CODE import java.io.*; public class Patter_of_your_Own_Name { public static void main(String args[])throws IOException { int time=1; BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); do { System.out.print("\n\t\t\tPLEASE,ENTER YOUR GOOD NAME IN CAPITAL LETTER           :"); String str=br.readLine(); int flag=0;
