Question 4.
Define a class named movieMagic with the following description:
Instance variables/data members:
int year – to store the year of release of a movie
String title – to store the title of the movie.
float rating – to store the popularity rating of the movie.
(minimum rating = 0.0 and maximum rating = 5.0)
String title – to store the title of the movie.
float rating – to store the popularity rating of the movie.
(minimum rating = 0.0 and maximum rating = 5.0)
Member Methods:
(i) movieMagic() Default constructor to initialize numeric data members to 0 and String data member to “”.
(ii) void accept() To input and store year, title and rating.
(iii) void display() To display the title of a movie and a message based on the rating as per the table below.
| Rating | Message to be displayed |
| 0.0 to 2.0 | Flop |
| 2.1 to 3.4 | Semi-hit |
| 3.5 to 4.5 | Hit |
| 4.6 to 5.0 | Super Hit |
Write a main method to create an object of the class and call the above member methods
Solution :
import java.util.Scanner;
class movieMagic
{
Scanner S = new Scanner(System.in);
Scanner StringScanner = new Scanner(System.in);
int year;
String title;
float rating;
movieMagic()
{
year = 0;
rating = 0.0f;
title = "";
}
void accept()
{
System.out.println("Enter the
name, year and rating of the movie.");
title = StringScanner.nextLine();
year = S.nextInt();
rating = S.nextFloat();
}
void display()
{
System.out.print("Title
:"+title+"\nYear :"+year+"\nRating
:"+rating+"\nMessage : Movie was a ");
if(rating<=2.0)
System.out.print("Flop");
if((rating>2.0)&&(rating<=3.4))
System.out.print("Semi-Hit");
if((rating>3.4)&&(rating<=4.5))
System.out.print("Hit");
if((rating>4.5)&&(rating<=5.0))
System.out.print("Super
Hit");
}
void main()
{
accept();
display();
}
}
Question 5.
A special two-digit number is such that when the sum of its digits is added to the product of its digits, the result is equal to the original two-digit number.
Example: Consider the number 59.
Sum of digits = 5 + 9 = 14
Product of its digits = 5 x 9 = 45
Sum of the sum of digits and product of digits= 14 + 45 = 59
Sum of digits = 5 + 9 = 14
Product of its digits = 5 x 9 = 45
Sum of the sum of digits and product of digits= 14 + 45 = 59
Write a program to accept a two-digit number. Add the sum of its digits to the product of its digits. If the value is equal to the number input, output the message “Special 2-digit number” otherwise, output the message “Not a Special 2-digit number”.
Solution :
import java.util.Scanner;
class Question5
{
Scanner S = new Scanner(System.in);
public boolean isSpecial(int x)
{
int prod = 1;
int r = x;
int sum = 0;
while(x!=0)
{
int d = x%10;
prod = prod*d;
sum = sum +d;
x=x/10;
}
if((prod+sum)==r)
return true;
else
return false;
}
void main()
{
System.out.println("Enter the
number");
int no = S.nextInt();
if(isSpecial(no))
System.out.println("It is a
Special No.");
else
System.out.println("Not a
Special No.");
}
}
Write a program to assign a full path and file name as given below. Using library functions, extract and output the file path, file name and file extension separately as shown.
Input: C:Users\admin\Pictures\flowers.jpg
Output:
Path: C:Users\admin\Pictures
File name: flowers
Extension: jpg
Output:
Path: C:Users\admin\Pictures
File name: flowers
Extension: jpg
Solution :
import
java.util.Scanner;
class
Question6
{
Scanner S = new Scanner(System.in);
String input,path,extension,filename,temp;
void method1(String str)
{
path = str.substring(0,(str.lastIndexOf('\\')));
extension = str.substring((str.lastIndexOf('.')));
filename =
str.substring((str.lastIndexOf('\\')+1),(str.lastIndexOf('.')));
System.out.println("Path : "+path+"\nFile
name: "+filename+"\nExtension: "+extension);
}
void main()
{
System.out.println("Enter the String ");
input = S.nextLine();
method1(input);
}
}
Question 7.
Design
a class to overload a function area() as
follows:
(i) double area(double a, double b, double
c) with three double arguments, returns the area of a scalene triangle using
the formula: area = √(s — a)(s- b)(s - c)
Where s = (a+b+c)/2
(ii) double area(int a, int b, int height) with
three integer arguments, returns the area of a trapezium using the
formula:
area = 0.5 X heightx(a+b)
(ii) double area(double diagonal 1, double
diagonal 2) with two double arguments, returns
the area of a rhombus using the formula:
Area =
0.5X(diagonal1 x diagonal2) [15]
import java.util.Scanner;
class Question6
{
Scanner S =
new Scanner(System.in);
String
input,path,extension,filename,temp;

method1(String str)
{
path = str.substring(0,(str.lastIndexOf('\\')));
extension = str.substring((str.lastIndexOf('.')));
filename = str.substring((str.lastIndexOf('\\')+1),(str.lastIndexOf('.')));
System.out.println("Path : "+path+"\nFile name:

Using the
switch statement, write a menu driven program to calculate the maturity amount
of a Bank Deposit. The user is given the following options:
(i) Term
Deposit
(ii)
Recurring Deposit
For option :-
(i) accept
principal(P), rate of interest(r) and time period in years(n). Calculate
Amount
and output the maturity amount (A) receivable using the formula A.= P[1 +(i/100)]
(ii) accept
Monthly Installment (P), rate of interest(r) and time period in months (n).
Calculate and output the maturity amount(A) receivable using the formula A=(Pxn)+((Pxnx(n+1)xr)/ (2x100x12) For an incorrect option, an appropriate
error message should be displayed. [15]
