- Visual Basic For tax purposes an item may be depreciated over a period of several years, n.With the straight line method of depreciation, each year the item depreciates by 1/nth of itsoriginal value. With the double declining balance method of depreciation, each year the itemdepreciates by 2/nths of its value at the beginning of that year. (In the final year it is depreciatedby its value at the beginning of the year.)Write a program using Visual Basic that performs the following tasks:1.1 Request a depreciation of the item, the year of purchase, the cost of the item, the number ofyears to be depreciated (estimated life), and the method of depreciation. The method ofdepreciation should be chosen by clicking on one of two buttons.1.2 Display a year by year description of the depreciation.arrow_forwardJava Program 01 - Theater Ticket System A small ten-seat theater has contracted you to build software which will reserve tickets. The theater has two rows of five seats each. Each row is referred to by number (1 or 2) and each seat in the row is referred to by letter (A, B, C, D, and E). When started, the program should ask the user for the row they prefer (row selection). If that row has no empty seats then the program should ask the user if they prefer the other row, if no then display a message stating the next show is tomorrow. Upon selecting a row, the program should present the user with a choice of available seats in the row. The user can then either choose a seat and print the ticket (in this case a simple message will suffice) or return to row selection. If a ticket is printed the program should return to row selection. The program terminates when all seats are reserved. Please enter a row: 1 Available seats: A B C D E Which seat, enter Q for none?: B You have…arrow_forwardAssignment2 Public Class name: wealth Write whole code inside main methodarrow_forward
- Math: pentagonal numbers) A pentagonal number is defined as n(3n-1)/2 , for n = 1,2, . . ., and so on. Therefore, the first few numbers are 1, 5 ,12, 22, ... Write a Java program with an object class called Pentagon and a test class called testPentagon. The Pentagon object class must contain a method with the following header that calculates and return a pentagonal number: public int calcPentagonalNumber(int n) Use the formula: n(3n-1)/2 In the test class: Make use of the calcPentagonalNumber(n) method in the Pentagon object class and display the first 100 pentagonal numbers with 10 numbers on each line. NOTE: NO marks if the pentagonal number is calculated in the test class. Your solution must be an object-oriented solutionarrow_forwardComputer Science C# Programming Object Orientation Please use Arrays or ArrayLists where appropriate Implement a menu driven program that has some operations for a food truck. A food truck has multiple food items as well as a menu which contains a selection of the food items which will be sold for that day. A maximum of 10 food items can appear on the menu for any day. For each food item keep a code, description, category, price and quantity in stock (code, description and category are not usually changed). Create a comma delimited text file called "items.txt" for 15 or more food items, indicating the item's description, category, price and quantity in stock. Read all the food items from the text file “Items.txt” Display all the food items available for this food truck. Continuously prompt the user for a food item’s code to be placed on the menu until the menu is full or the user enters -1. Note that only food items which have a positive quantity in stock may be added to…arrow_forwardCharge Account Validation Using Java programming Create a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.arrow_forward
- Which import statement should be included in the source code of a class so that the Math class is explicitly imported? Choose from the given choices. *arrow_forwardTranscribed Image Text JAVA Programming Problem: In the game of "Assassin's Creed", you control a ship with a cannon which is attacking a large enemy Assassin's Creed, armed with many guns. Your goal is to destroy as many of the guns as possible. The battle field is a 2D Cartesian grid, where your cannon is located at the origin. The enemy Assassin's Creed is a horizontal line segment located from the coordinates (X1, Y) to (X2, Y). There are exactly (X2 - X1 + 1) guns on the ship, located at the integer points (X1, Y), (X1+1, Y), ..., (X2, Y). However, the problem is, you cannot always fire at a gun. There are supernatural rocks located at all points of the battlefield whose X and Y coordinates are both integers. In order to fire successfully at an enemy's gun, the line connecting your cannon and that gun must not go through any rocks. Develop a JAVA code to output the number of the enemy battleship's guns that your cannon can destroy. Test Case Result 1 2 2 -2arrow_forward(Simulation) Write a program to simulate the roll of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like, with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)arrow_forward

A few examples of such fields would be name, brand, etc. Append the class with methods that allow a customer to buy that product and append the number of times the product is sold. The customer will be subjected to 13% tax on each buy, you will calculate the payable amount and display it on the console on each buy.arrow_forwardCreate a PIN number verification program The program asks for numbers with 4 digits The program should print an error message if The number has more or less than 4 digits The PIN is different than 3454 If the PIN is right, it should print a success message.
