Ulma's Ungulates

Write a program to compute the price of renting an animal from Ulma's Ungulates. You can rent either a llama, or a camel. The price depends on:

• Which animal you choose.
• How far you want to ride the aminal.
• Whether you want to rent a saddle as well.

The worksheet starts like this:

The user fills in the three fields above the Run button, and clicks Run. Here's some output:

Here's another sample:

Validate all the input, using the following rules:

• The animal input must be either L or C. Case doesn't matter. Use trim() to remove unwanted spaces.
• The number of miles must be numeric, and between 3 and 50 inclusive.
• Saddle is either Y or N. Case doesn't matter. Use trim() to remove unwanted spaces.

If there are any input errors, show a message, and end the program. For example:

Output the full name of the animal, the warning, and the cost.

• Llamas cost $20 per mile.
• Llama saddles rent for $120.
• Camels cost $12 per mile.
• Camel saddles rent for $180.

The usual coding standards apply.
