- 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 methodIn 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…In Java Write a program that reads the student information from a tab separated values (tsv) file and creates a text file that contains student information together with the course grades of the students.

- The teacher at a school needs help grading an exam with a number of True/False questions. The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade. Assume the following grade scale will be used: 90%-100%, A; 80%-89.99%, B; 70%-79.99%, C; 60%-69.99%,…Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade.

A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter…IN JAVA ONLY PLEASE.

- Write a program that reads the contents of the two files into two separate lists. The user should be able to enter a boy’s name, a girl’s name, or both, and the application will display messages indicating whether the names were among the most popular. your program should read the files into separate lists for boys and girls names the program should accept either a girl name or a boy name or both, entry of a NULL i.e. just pressing the "enter key" results in no search for that entry the program must continue to run until told to stop by the person running the program using any method of your choice report on the success or not of each attempt to locate a name in the popular names filesWrite a program that will ask the user for their grocery list, one item at a time, and will write it to a file called groceries.txt.

Assign a point value to each based on your estimate of its likelihood to be in a phishing message (e.g., one point if it's something likely, two points if modereratly, or three points if highly likely). Write an application that scans a file of text for these terms and phrases. For each occurance of a keyword or phrase within the text file, add the assigned point value to the total points for the number of occurences and the point total. Show the point total for the entire message. (Write the program in Java)

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…
