The weather in Tampa Florida is warm most all year round. This does lead to the interesting scenario where some people have never seen snow. To help enlighten those individuals on the wonders of snow we have designed our very own Snow Factory. We as that you help make this a reality by implementing our designs

We require an Abstract class called SnowFlake. SnowFlake will require any class extending it to set the following variables:

• type • radius • diameter • meltModifier (0.05) • Random Number Generator (static) • snowFall (static)

The following methods are required: • getType() • getDiameter() • getRadius() • toString() The follwing method is abstract: • melt();

The list to the right contains the  common types of SnowFlakes. Create a class that extends the SnowFlake class for each of them. Source: http://www.snowcrystals.com/guide/snowtypes4.jpg Each snowflake should do the following:

1. Initialize the variables in the super class

1. The diameter should be of a random size of type double multiplied by a factor of randomly numbers from 8 to 10.

2. The radius is half the size of the diameter

3. The type is the one defined in the table

2. the melt method should reduce the size of the diameter by a factor of (the type plus the meltModifier). This can be accomplished by dividing the diameter by (the type plus the meltModifier) Now that we have the types of snow flakes defined we need to consider a Factory that will produce them. Forutunately, a skeleton has been provided. You will be required to make some changes to make the program work. We will focus on the recursive function:

createSnowBall.

1. createSnowBall

1. This method has three parameters 1. desiredSize 2. currentSize 3. ArrayList snowBall

2. This method will recurisively call the create snowball method untill the desired size is reached.

3. If the current size is not greater than the desired size 1. we will add a snowflake to the snowball using the createSnowFlake method 2. increase the current size to account for the new snowflake.
