Problem Write a program that simulates a vending machine. Products can be purchased by inserting coins with a value at least equal to the cost of the product. A user select a product from a list of available products, add coins, and either gets the products or gets the coins returned. The coins are returned if insufficient money was supplied or if the product it's sold out. The machine does not give change if too much money was added. Products can be restocked and money remove by an operator. Your solution should include a class VendingMachine that is not coupled with the Scanner or PrintStream classes Sample output S)how products IDnsert coin B)uy A)dd product R)emove coins Quit Description Cookie Price: 2.00 Quantity: S)how products I)nsert coin B)uy A)dd product R)emove coins Quit Price: 1.00 Quantity: S)how products I)nsert coin B)uy A)dd product R)emove coins Quit Cookic @ $2.0 Candy @ $1.0 S)how products Insert coin B)uy A)dd product R)emove coins Quit A) Cookie @ $2.0 B) Candy @ $1.0 Insufficient money S)how products IDnsert coin B)uy A)dd product R)emove coins Quit A) nickel @ 005 B) dime@ 0.1 C) quarter @ 025 D) dollar @ 1.0 S)how products Dnsert coin B)uy A)dd product R)emove coins Q)uit A) nickel @ 0.05 B) dime @ 0.1 C) quarter @ 025 D) dollar @ 1.0
