Write a simple cash register class. (Use Java) Each cash register should keep track of the number of items checked out and the total cash in the register. We are only concerned with the number of items to check out and their prices. No need to handle item names, SKUs, taxes, etc... It should have the following methods (use static when appropriate): checkout( ) Takes two forms. If there is only one parameter that is the cash received and there is only one item checked out. If it has two parameters, the first parameter should have the number of items checked out and the second parameter is the price per item. cashout( ) Reset the number of items and total cash to zero for a cash register getItems( ) Returns the number of items in the cash register getTotalCash( ) Returns the total cash in the cash register getAveragePricePerItem( ) Returns the average price per item checked out by the cash register getRegisterCount( ) Returns the number of cash registers created getAllItems(...

Can each class be done please I am not sure how to do each one. In java Make a program with classes named Vehicle, LandVehicle, AirVehicle, Car, Truck, Glider, Balloon, VehicleFactoryMain, MyFileManager. The Vehicle Inheritance looks like this: Note: Vehicle should also have a range. Make sure to override the toString() method for returning a String that includes all the information about an instance of a vehicle. VehicleFactoryMain will use these classes to make a random number and assortment of vehicle types. For example: Car - red, 526Km,1524Kg, 1988Kg, 1001Kg, gas, 4-wheels, 2-doors, fastback. Balloon - orange, 234Km,320Kg, 423Kg, 256Kg, gas, 950m, hot air. For the various ranges, altitudes, and weights set a max and min value and randomly choose between those. For values that have types (hot-air, hydrogen, helium or gas, electric, diesel, kerosene, methane,none) make a static array in the class and randomly choose one of the values. Have the factory select a random number...

Use Java program to add a method printReceipt to the CashRegister class. The method should print the prices of all purchased items and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information. Here is the CashRegister class: /** A cash register totals up sales and computes change due.*/public class CashRegister{ private double purchase; private double payment; /** Constructs a cash register with no money in it. */ public CashRegister() { purchase = 0; payment = 0; } /** Records the sale of an item. @param amount the price of the item */ public void recordPurchase(double amount) { purchase = purchase + amount; } /** Processes a payment received from the customer. @param...
