You are to create a program to calculate a College bill for a student. You will have two new user defined classes.

The first user defined class will have a default constructor that will assign the following data to variables to your choice. Therefore, the only this thing this class will do is to assign these values to variables:

1. Cost of the tuition rate per credits = $750
2. Cost of the technology fee =$50
3. Cost of three levels of meal plans,

• gold,=$3,500
• silver=$3,000
• bronze=$2,500

1. The second userdefined class will contain the methods:
2. a default constructor that has the first class above passed to itand data from the first class is assigned to variables of your choice in this second class

A method that prompts the user for the following data:

• student name
• number of credits
• room amount
• which meal plan the student wants(gold, silver or bronze)

A method to calculate the following:

• cost of room and board= (cost of the meal plan + room amount) You will need an if statement to calculate the meal plan based on the meal plan costs passed in
• tuition = number of credits * the tuition rate passed in
• final technology fee = technology fee passed in * number of credits
• final bill = room and board + final technology fee + parking pass (passed in) +tuition

A method to print all of the following data in one dialog box using currency format (example of using currency formatting is included with this assignment)

• student name
• number of credits
• tuition the student owes
• room and board amount
• parking pass amount
• final technology fee
• final bill due

What to turn in:

• Create a word document and first copy your code
• Then copy a screen shot of the final output
• Submit the word document to blackboard

PLEASE NOTE: You text in the word document MUST be black. Submissions with light text will not be accepted.
