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
  • Cost of parking pass=$200
    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.
