- Computer Science JAVASCRIPT .xlsx parser I need to write a public class that reads an .xlsx file and returns an array of data in javascript. The array would be all of the data inside of the file. The file itself is going to be inside of a folder(downloadedFIles) inside of my project. So the public class will need to account for that.arrow_forwardA file USPopulation.txt contains the population of the US starting in year 1950 and then each subsequent record has the population for the following year. USPopulation.txtDownload USPopulation.txt Write a program that uses an array with the file that displays these in a menu and then produces the results. This is not an Object Oriented Program but should be a procedural program, calling methods to do the following: 1: Displays the year and the population during that year 2. The average population during that time period (Add up the populations of all records and divide by the number of years). 3. The year with the greatest increase in population - print the year and that population and that amount. To figure this out, compare the difference in population before of say year 1950 and 1951, store that difference somewhere. Compare 1951 with 1952, find that difference. Is that difference greater than the stored difference? If so, move that the the maximum place. 4.…arrow_forwardStream : JAVA Tech Module :1 Project:1 Given the following table containing information about employees of an organization, develop a small java application, which accepts employee id from the command prompt and displays the following details as output: Emp No Emp Name Department Designation and Salary You may assume that the array is initialized with the following details: Emp Emp Join Date Desig Dept Basic HRA IT No. Name Code 1001 Ashish 01/04/2009 e R&D 20000 8000 3000 1002 Sushma 23/08/2012 PM 30000 12000 9000 1003 Rahul 12/11/2008 k Аcct 10000 8000 1000 1004 Chahat 29/01/2013 r Front 12000 6000 2000 Desk 1005 Ranjan 16/07/2005 m Engg 50000 20000 20000 1006 Suman 1/1/2000 e Manu 23000 9000 4400 factur ing 1007 Tanmay 12/06/2006 PM 29000 12000 10000 Salary is calculated as Basic+HRA+DA-IT.

- in C#, Visual Basic Write an app for Boston Airlines that allows a customer to reserve a seat on the airline’s only plane (capacity: 10 seats). Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message “Next flight leaves in 3 hours."arrow_forwardAssume numbers is a vector that contains these integers:2 4 6 8 10Then the following code executes:numbers. resize (9) :numbers. resize (11, 5) ;What does the vector contain now?O 11 1111 11 11 0 0 0 0 2 4 6 8 10000002468 10 5 502 4 6 8 10 0 0 0 0 11 11 11 11 1105500002468 100246810 000055Assume vec1 is a vector that contains these integers:10 20 30 40 50 60 70 80 90 100And vec2 is a vector that contains these integers3 6 9 12 15Then the following code executes:vecl.resize(7):vecl.swap (vec2) ;What do the vectors contain now?Cvec1 contains 3 6 9 12 15vec2 contains 10 20 30 40 50 60 70vec1 contains 3 6 9 12 15 0 0Ovec2 contains 10 20 30 40 50 60 70vec1 contains 3 6 9 12 15O vec2 contains 50 60 70 80 90 100vec1 contains 0 0 3 6 9 12 15O vec2 contains 50 60 70 80 90 100This code creates a compiler error.arrow_forwardProject 5 - Magic Squares Objectives The objective of this project is to have students practice with two-dimensional arrays and loops. Specifications In this project, you will write code to determine if a two-dimensional array of ints is a Magic Square. For a two- dimensional array of ints to be a Magic Square all of the following must be true: 1. The array must be square - in other words, the lengths of all rows and all columns must be the same. 2. The array must contain all integers from 1 to n*n, where n is the length of the rows and columns. 3. The sum of the numbers in each diagonal, each row, and each column must be the same. You have been given two classes: • MagicSquareTest.java - Contains JUnit test cases for the MagicSquare class. Your code must pass all these tests. • MagicSquare.java - contains static methods to determine if a two-dimensional array of ints is a Magic Square: o isMagicSquare() - returns true if a two-dimensional array of ints meets all the criteria to be a…arrow_forward
- A vector is an ordered list of items of different data types. Each item in a vector is called an element. Also, programmers must include the statement #include <vector> at the top of the file when planning to use vectors. true or falsearrow_forwardFunctions with 2D Arrays in Java Write a function named displayElements that takes a two-dimensional array, the size of its rows and columns, then prints every element of a two-dimensional array. Separate every row by a new line and every column by a space. In the main function, call the displayElements function and pass in the required parameters. Output 1 2 3 4 5 6 7 8 9arrow_forwardJava - Functions with 1D Arrays Create a program that asks the user for the size of an integer array and the elements of the array. Then, create a function called maxArray() with the following details: Parameters: An integer array The size of the integer array Return type - int Return value - the maximum value of the integer array Call the function you created in the main and pass the integer array and its size to it. Make sure to store the return value in a variable so you could print it afterwards. Input 1. First line contains the size of the array 2. Succeeding lines are the elements of an array 3. First line contains the size of the array 4. Succeeding lines are the elements of an array 5. First line contains the size of the array 6. Succeeding lines are the elements of an array 7.

- This assignment utilizes a class in an application that might be useful in the “real world.” It requires the sorting of, and computation with, data involving temperatures. Requirements: You are working for a meteorologist to maintain a list of temperatures and some related statistics for a month. Class and Data members: Create a class called Temperature that stores temperature readings (integers) in a vector (do not use an array). The class should have data members that store the month name and year of when the temperature readings were collected. Constructor(s): The class should have a 2-argument constructor that receives the month name and year as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the month and year variables. A member function that adds a single temperature to the vector. Both negative and positive temperatures are allowed. Call this…arrow_forwardIn C Programming Write a main function that declares an array of 100 ints.

Allow the user to enter a course name and display the corresponding time and instructor. If the course exists twice, display details for both sessions. If the course does not exist, display an error message. Save the file as TimesAndInstructors.javaarrow_forward
