Java

Item class

Add private data fields (instance variables) for the items name, price, and quantity.

public Item()

sets price and quantity to 0 and name to the empty string.

public Item(String name, double price, int quantity)

Use the setters (mutators) to set the instance variables to the parameter data.

Add public accessors and mutators for name, price, and quantity. Guard against a negative price or quantity by setting the data member to 0.

public void reduce(int amount)

decrements the quantity field by amount if amount > 0 and amount <= quantity.

Sample: Pepsi, $1.25, 7 remaining

public String toString()

(Overrides the object class toString method)

Displays the candy name, price, and quantity with comma separators. There is no additional spacing or price formatting
