The fleet class includes a constructor that creates an array to store the entire fleet of Delta airlines. It also had method to read and write files, sort the array by registration number, add and remove aircraft, display the fleet and maintenance lists, update aircraft miles and maintenance , and display information about specific aircraft. Could you please explain it in Java? Fleet class:Instance VariablesAn array that stores Aircraft that represents Delta Airlines entire fleetA variable that represents the count for the number of aircraft in the fleetMethods:o Constructor-One constructor that instantiates the array and sets the count to aeroreadFile()-This method accepts a string that represents the name of the file to beread. It will then read the file. Once the data is read, it should create an aircraft andthen pass the vehicle to the addAircraft method. It should not allow any duplicationof records. Be sure to handle all exceptions.o writeFile()-This method accepts a string that represents the name of the file to bewritten to and then writes the contents of the array to a file.

For each item that doesn't match, it will copy the contents to the newarray. It will not copy the contents of the aircraft that is found. In other words, allaircraft in the array will be moved up a position to fill in the gap in the array.nu class:stance Variables:o An array that stores all of the menu item options

Homework - identical arrays for one-dimensional: Write a test program which prompts a user to enter the size of two arrays as well as to fill their elements. After that, the program checks the same contents of the elements of the two arrays. If these arrays are equal, the program displays message which is "The two arrays are identical". If not equal, displaying "The two arrays are not identical". Write an equals method that reads two arrays and displays these messages above.
C++HurdleWords The HurdleWords class is mostly provided to you. HurdleWords is constructed from two files in the data/ folder: ● valid_guesses.txt (all 5 letter guesses considered to be valid words to guess), and ● valid_hurdles.txt (all words that may be selected to be the secret Hurdle.) ● Note: you may edit both text files if you’d like to add custom words to your game. HurdleWords stores all potential valid Hurdles from valid_hurdles.txt into a vector of strings (valid_hurdles_), and all valid guesses from valid_guesses.txt into an unordered set of strings (valid_guesses_). A set is simply a data structure that contains no duplicates and allows for a speedy lookup to check if a given element exists within the set. Because there are over 10,000 valid guesses, we store them in an unordered set to leverage their speediness, as you will need to check if a user-submitted guess is considered valid (i.e. their guess is considered a valid guess in the dictionary). You are responsible for…
C# Windows Application Tic-Tac-Toe Simulator- Create an application that simulates a game of tic-tac-toe. Figure 7-49 shows an example of the application’s form. The form shown in the figure uses eight large Label controls to display the Xs and Os. The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element. The number 0 represents the letter O, and the number 1 represents the letter X. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.
10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
Flowchart for student interface program please. Create a program to enter grades and calculate averages and letter grades. Need a class which will contain: Student Name Student Id Student Grades (an array of 3 grades) A constructor that clears the student data (use -1 for unset grades) Get functions for items a, b, and c, average, and letter grade Set functions for items a, n, and c Note that the get and set functions for Student grades need an argument for the grade index. Need another class which will contain: An Array of Students (1 above) A count of number of students in use You need to create a menu interface that allows you to: Add new students Enter test grades Display all the students with their names, ids, test grades, average, and letter grade Exit the program Add comments and use proper indentation. Nice Features: I would like that system to accept a student with no grades, then later add one or more grades, and when all grades are entered, calculate the final…
Grade Book A teacher would like to assign a letter grade to a student, based on student's test score. Write a program to help this teacher managing her students' test score. Use the following grading scale to assign a letter grade to a student. Test Score Letter Grade 80 - 100 A 70 - 79 B 60 69 C 50 - 59 0- 49 F Your program must have an array of string objects to hold the student names and an array of int to hold the student scores. Let the teacher determines the number of students and ask the teacher to enter the information for each student. Your program should have the following programmer-defined functions: getInput () - to read the students name and scores from user getGrade () - to determine the letter grade corresponding to the score getReport () - to determine the maximum, minimum, average and standard deviation of the scores Display an error message if the teacher enter mark below 0 or above 100, and keep asking for a valid value. The program should also be capable of…
