Using Dr. Java

Objective:

Write a program that creates a class Apple and a tester to make sure the Apple class is crisp and delicious.

First create a class called Apple

Write a class file called Apple that DOES NOT HAVE a main method Some of the attributes of Concert are

Type: A string that describes the apple. It may only be of these following types

Red Delicious Golden Delicious Gala Granny Smith

Weight: A decimal value representing the apples weight in kilograms. The weight must be between 0kg and 2kg Price: The price per apple. This must be a non-negative decimal value.

Create the following Constructors

Default sets everything to default values and has no parameters

Accessors and Mutators for each variable

MAKE SURE THE MUTATORS CHECK FOR VALID VALUES!

Create the following Methods

toString: Returns a string with all of the instance variable values

Ex: Name: <> Weight <> Price <>

equals: This method returns a Boolean and takes in another instance of an apple. It returns true if all of the instance variables equal the instance variables in the other apple

Finally create a class called AppleTester

This class DOES HAVE a main method Create at least 3 different types of apples Test if the accessors, mutators, and other methods work as intended.

Example Dialog:
