10) [18 pts] An online shopping site offers a variety of laptops, printers, and monitors. A customer may also buy all in one (Allinone) including these three. The price of Allinone is the sum of the two highest-priced items in the Allinone, i.e. one item with the lowest price is free. Each item has a name and a price. The four types of the items are represented by the four classes Laptop, Printer, Monitor, and Allinone. All four classes implement the following Item interface. The following diagram shows the relationship between the Interface Item and the classes Laptop, Printer, Monitor, and AllinOne. For example, assume that items sold on the site are as follows. The objects listed under each heading are instances of the class indicated by the heading. - Customers may create Allinone items, each of which includes a laptop, a printer, and a monitor. - The name of the Allinone is composed of the names of the laptop, the printer, and the monitor, in order, each separated by "/" and followed by a space and then "Allinone". - The price of the Allinone is the sum of the two highest-priced items in the Allinone; i.e. one with the lowest price is free. An Allinone consisting of an Apple MacBook Pro, a Canon LBP610, and an Apple ThuderBolt will have the name "Apple MacBook Pro/Canon LBP610/Apple ThuderBolt Allinone" and a price of $3800.00 (the two highest prices are $\$ 2000.00$ and $\$ 1800.00$ ). Similarly, an Allinone consisting of a Dell XPS, an HP Deskjet 5820, and a Dell Curve GT will have the name "Dell XPS/HP Deskjet 5820/Dell Curve GT Allinone" and a price of $\$ 2400.00$ (the two highest prices are $\$ 1500.00$ and $\$ 900.00$ ). Write the class AllinOne that implements the interfaces Item and Comparable. Your implementation must include a constructor that takes three parameters representing a laptop, a printer, and a monitor. The main method is given to test the result.
