i need answer within 6 or 7 hours

P2: Write a class Item that stores information about an object in a store. It should have variables for: the name of the item the full price of the item the sales price of the item Each price of the item should be stored as a double. Write two constructors for this class: one which has the name of the item, the full price, and the sales price as parameters, and one which only has the name of the item and the full price as parameters. In the second case, the sales price should be set to half the full price. Write a method called format which takes a double as its parameter and returns a string representing the double as a price. Specifically, put a $ in front of the double value, and round the value to have exactly 2 decimal places. If the double value is less than e, return $0.00. If the double value only has one decimal place, add a e at the end (ex. 6.7 becomes $6.70)
