Question

Assume that all courses are 3-units. Write a program GPA.java that performs the following, • Ask user to input the number of As, Bs, Cs, Ds and Fs a student received so far. Save these in an array. (A : 4.0 Grade points, B: 3.0, C: 2.0, D: 1.0, F: 0.0) • Find the grade that the student got the most of. • Calculate overall GPA by looping through the array • Print out result One sample output is: Enter number of A B C D and F grades for the student: 5 4 3 2 1 The grade that student got the most is: A Student Overall GPA: 2.67 (Hint: GPA calculation: (#As*4.0 + #Bs*3.0 + #Cs*2.0 + #Ds*1.0 + #Fs*0.0)/total #courses For above example (5*4.0+4*3.0+3*2.0+2*1.0+0)/15 = 2.67, you need to use a loop for calculating the GPA) Assume that all courses are 3-units.
