Develop a simple gradebook management system in Java that allows professors to record and retrieve student grades from a file. The system should have the following features: 1. Add a Student Record: This feature should allow the user to input student details like Student ID, Name, and Grade. This data should be appended to a file named gradebook.txt. 2. Retrieve a Student Record: The system should retrieve a student's grade using the Student ID. 3. List All Records: Display all student records present in the file. 4. Update Student Grade: Update the grade of a student using their Student ID. 5. Delete Student Record: Remove a student record from the file using their Student ID. File Structure (gradebook.txt): Each line in the file represents a student record and is structured as: [Student ID], [Student Name], [Grade] For example: S1001,John Doe, A S1002, Alice Smith, B+

This project involves generating a boarding pass ticket and storing it in a file. The application should take the passenger details as input. The details of the boarding pass are to be stored in a file. The details should include valid data such as: name, email, phone number, gender, age, boarding pass number, date, origin, destination, estimated time of arrival (ETA), departure time. The application should generate a boarding pass ticket using the boarding pass details. The generated ticket should contain the following information: Boarding Pass Number, Date, Origin, Destination, Estimated time of arrival (ETA), Departure Time Name, Email, Phone Number, Gender, Age Total Ticket Price The user will be required to enter their Name, Email, Phone Number, Gender, Age, Date, Destination, and Departure Time into the console or GUI. From the input the computer must generate the ETA and Ticket Price. The computer must generate the boarding pass number ensuring the number is unique. All…

DescriptionWrite a program to compute average grades for a course. The course records are in a single file and are organized according to the following format: each line contains a student's first name, then one space, then the student's last name, then one space, then some number of quiz scores that, if they exist, are separated by one space. Each student will have zero to ten scores, and each score is an integer not greater than 100. Your program will read data from this file and write its output to a second file. The date in the output file will be nearly the same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. and the name of the output file with argv[2].The output file must be formatted as described below: 1. First and last names…

Write a Python program for a movie database management system. The program should allow users to add movies, remove movies, and display the current collection. Each movie has a title, director, release year, and rating. The program should have the following features: 1. A menu-based system that allows users to choose between adding a movie, removing a movie, and displaying the collection. 2. When adding a movie, the user should input the title, director, release year, and rating. 3. When removing a movie, the user should input the title of the movie to be removed. 4. Display the current movie collection with details of each movie, including title, director, release year, and rating. Make sure to include comments that explain the purpose of the program, input and output details, and any complex logic. Use self-documenting variable names, white spaces, and indentation for readability. Test your program with sample data to ensure correct functionality and provide screenshots of two…

Create a datafile that contains the first name, last name, gender, age, height, smoking preference, eye color and phone number. Add a variety of records to the file. A sample file looks like: Write a program that opens the file and reads the records one by one. The program will skip any records where the gender preference is not a match. Of those records that match the gender preference, check to see if the age and height are between the maximum and minum preferences. Then check to see if the smoking preference and eye color are also a match. If at least 3 of the remaining fields match, consider the record a partial match, and print it in the report. If all 4 of the remaining fields match, the record is a perfect match and print it in the report with an asterisk next to it. At the end of the program, close the file and report how many total records there were of the specified gender, how many were a partial match, and how many were a perfect match.
Java Programing Joyce Farrell 13-8 Create an application named StudentsStanding.java that allows you to enter student data that consists of an ID number, first name, last name, and grade point average. Have the program accept input until ZZZ is entered for the ID number. Depending on whether the student’s grade point average is at least 2.0, output each record either to a file of students in good standing (StudentsGoodStanding.txt) or those on academic probation (StudentsAcademicProbation.txt). Create an application named StudentsStanding2.java that displays each record in the two files created in the StudentsStanding application. Display a heading to introduce the list produced from each file. For each record, display the ID number, first name, last name, grade point average, and the amount by which the grade point average exceeds or falls short of the 2.0 cutoff. For example, the output should be formatted as follows (note that the student info may vary): Probationary Standing…

You are asked to develop an application that does the following: 1. The application should read the records from the user (String Name and String ID) and write them into a text file named (Employees.txt). The text file should be structured as follow: Sara Ahmad 123123 121122 John 123 Mohammed 12345 2. The user is asked to enter the values for records untih the user enters the value zero (0) for the name then the loop should be terminated. 3. Then, the application should read and check each record in the text file and print out all the records that have an ID less than 6 digits. Note: • The file should be opened only once for writing otherwise the previous content will be truncated. • Make sure you handle all expected exceptions that might be caused by the provided code.
