Frames Unlimited is a wholesaler that specializes in picture frames. The company stores its product information (each item’s number, name, size and price) in a sequential access file named pictureFrame.txt.
You need to create a report using the pictureFrame.txt sequential access file. The report should contain a list of all picture frames with a size of 5×7. The report will be saved to another sequential access file named pictureFrame57.txt. Your first step is to ____.
a.
determine whether the pictureFrame.txt file exists
b.
declare a StreamReader variable for the input file
c.
open the pictureFrame.txt file for input using the OpenText method
d.
open the pictureFrame57.txt file for output using the CreateText method
PHONE DIRECTORYDescription: Create a phonebook directory that will store the contact numbers of N persons. Your program should allow the user to add, view, delete, and update the contacts in the phonebook. Note that one person can have multiple contact numbers. The program will stop when the user command is ‘X’. Program command and entry should not be case-sensitive. That means commands ‘I’ or ‘i’ and the name “Jacky” or “JACKY” are the same. Each contact number can be 7 digits or 11 digits only.
The user should input a string containing the command, name, and contact number(s) (Limit the contact number of each person to three). This string should be broken down into fields in order to separate the different values and store them in their appropriate variables.
Use linked list in the implementation. Your node must declare at least four instance variables.
Program flow:
Command> I Jacky 09211234567 Remarks: New contact has been added. Command> V Jacky Contact…

When the user fills out new car information and clicks "Add", the new car object is created, the form is
closed, so that the main form is shown again, and the newly created car object is added to the list of
cars. When "View cars" button is clicked, the following form shows, displaying all car objects currently in
the list (use Getlotel) function here. You will also have to send the list of cars from the main form to tis
form. To do this in the view form have a public variable for list of cars, and assign to it the list of cars
from the main form).

- A MyPetStore sells many pets and their accessories. As new pets are added to the MyPetStore, theirinformation is entered into a flat text file. Each month, the manager requests a listing of all pets sorted bytheir price. You must write a program to produce a report of MyPetStore and their types sorted by their pricesfrom the data in the flat text file. Below is a description of the information on the text file:• The first entry is the number of animals on the file (numeric) •The fields below repeat for each animal:o Pet name (String)o Birthdate (java.time.LocalDate)o Price (numeric)o Species Type (String)o Special feature (boolean or String)The animals sold by the MyPetStore are of six types: Dogs & Cats, Reptiles, Birds, Rabbits & SmallAnimals.For Dogs & Cats, the special feature field on the flat file is the breed of the animal (String).For Reptiles, the special feature field is the blood type (warm vs cold-blooded, String).For Birds, the special feature field is the…arrow_forwardYour goal is to implement an application that reads a file, modify its content, and writes the modification back to the same file. The file includes 2 lines of integers. The first line indicates which integer on the second line has been selected (active). And the second line lists all the integers in the list (maximum of 10). Your application should have a menu that is constantly displayed on the screen (see the menu below). Right below the menu, the program should display list of all integers in the file (second line). Also, it should show which integer is currently selected (active) by displaying an arrow to its left. The user should be able to select a menu item by entering its associated key and pressing the Enter key on the keyboard. “Select Down” selects the next item in the list. If the item at the end of the list is selected, this option selects the first item in the list. “Select Up” selects the previous item in the list. If the first item is selected, this option selects the…arrow_forwardCase Problems - 1- In Chapter 8, you modified the EventDemo program for Carly’s Catering to accept and display data for an array of three Event objects.

- In Java Oleae nust read a file A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…arrow_forwardFinish this program from the code posted below!
