With your current Java knowledge, you have decided to write a program that will calculate a student's GPA for the current semester. The program should prompt the user to enter four values representing the number of A, B, C and Ds earned for the semester then calculate and display the GPA. When writing the program, consider the following: The program should prompt the user to enter four INTEGER values representing the number of grades earned for each letter grade. GPA is calculated by dividing the total points earned by the total number of credits attempted. All of the courses taken for the semester are 4 credits. ● . ● ● ● ● ● To determine the calculations, A grades have a point value of 4, B grades a point value of 3, C grades a point value of 2 and D grades a point value of 1. Total Number of Credits Attempted = Sum of Number of Courses multiplied by the number of credits for each course. ● The total points earned is the sum of the credit hours multiplied by the point value for each letter grade. Use the Scanner class to accept the user input. The output should be displayed with 3 significant decimal places. Explicit casting and constant representation should be used where applicable. • Output should be displayed in full sentence. Save the code as GPAScanner.java Sample Program Execution: GPA Calculator Enter the number of A grades earned: 3 Enter the number of B grades earned: : 1 Enter the number of C grades earned: 0 Enter the number of D grades earned: : 2 Grade A B C D Total Credit Hours Grade Points. 12 48 4 0 8 24 12 0 8 68 The GPA for attempting 24 credit hours and earned grades is 68/24 = 2.833
