Homework SourseQuestionsUpdate the determineDiscount method to set the disc
Questions:::::•Update the determineDiscount method to set the discount flag properly
•The base price of the pizza should vary based on which size is ordered
•Update the getBaseCost method to properly set the base cost of the pizza
•The default crust is hand-tossed
•Update the getCrustType method to properly set the string for the crust type chosen
•The system should default to hand-tossed if a proper choice is not made
•Use a switch statement to accomplish this task
•The base cost needs to be updated for various reason
–Discount
–Toppings
–Tax
•Update the updateCost method to appropriately update the cost based on a change amount sent to the method
