Lab 08: Loops Overview: This lab involves the development of a program to compute the Grade Point Average (GPA) of a student based on the grade and credits for each of student's courses. For each course, the needed information is the final letter grade for the course and the credits for the course. A letter grade can be converted to "points" for the GPA calculation using the following table: Points 4 Multiplying the credits for one course by the letter grade points gives the "weighted points." For example, a grade of B in a 4- credit course yields 12 weighted points. The formula to compute the GPA for all courses is as follows: Grade A or a B or b C or c D or d F or f 2 0 (sum of weighted points) (sum of credits) Your problem is to develop the class Gpa that will compute a student's GPA and a test class ComputeGpa to prompt for the students for grade and credits for each course. The main method will then print the GPA after all course data have been entered Based on the description above, what are the attributes of the class GPA? Based on the description above, what are the methods of the class GPA
