These are the write code problems and mixed up code puzzles used by the Unit 3 Toggle Code Practice page. Each problem has two copies that differ only in their label: the Get Help puzzle for the copy whose label ends in -ct-static is always the mixed up code puzzle below it, while the other copy’s Get Help puzzle is personalized by CodeTailor when the course has an API token. The practice page assigns each student one copy of each problem at random.
Write a constructor for the Student class. It takes a name (a String), a grade (an int), and a gpa (a double), in that order, and sets the matching instance variables. Then write a toString method that returns the student’s information in the form name (grade grade): gpa, for example Ana (grade 10): 3.8.

Every PizzaOrder shares the same price per slice, stored in the static variable pricePerSlice. Write a static method setPricePerSlice that takes a doubleprice and changes pricePerSlice to it. Then write a getTotal method that returns the order’s total cost: slices times pricePerSlice.
