Need help writing a java program that uses inheritance.

Create an application that allows the user to put different types of fruit into a basket. First create a base class called Fruit. Using inheritance, create at least 5 types of specific fruits (e.g. Apple, Banana, Pear, Orange, Grape) and define those classes as subclasses from Fruit. Each Fruit object has the following fields: color, weight, price. In addition, each specific fruit can have additional fields. Examples are, an Apple can have a field AppleSubtype, which can hold the apple's subtype (e.g. Granny Smith). A banana can have a field called Length. Grapes can have a field for number of grapes on one vine. Be creative and add at least 1 field to each individual, specific fruit class. The user has a basket (an array) that can hold 10 times. The user is asked how many of each items he wants to add to the basket, until either the basket is full, or each fruit has been offered to the user. Once the basket is full or the user chooses not to add 10 items, let the user know what the total weight of the basket is, and what the total price of the fruits is. You can decide yourself on the weights and the prices, but use somewhat appropriate numbers.
