Write a program to read a list of exam scores given as integer percentages in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category as follows: 90 – 100 is an A, 80 to 89 is a B, 70 to 79 is C, 60 to 69 is D and 0 to 59 is an F. Use a negative number to indicate the end of the input. Give the percentage of total for each letter grade, Give the range of the scores: lowest and highest and the average score.
I need help with creating a Java program based with the loop methods:
Write a program to read a list of exam scores given as integer percentages in the range 0 to 100. Display the total number of grades and the number of grades in each letter-grade category as follows: 90 – 100 is an A, 80 to 89 is a B, 70 to 79 is C, 60 to 69 is D and 0 to 59 is an F. Use a negative number to indicate the end of the input. Give the percentage of total for each letter grade, Give the range of the scores: lowest and highest and the average score.
The output is shown below:
98 87 86 85 85 78 73 72 72 72 70 66 63 50 -1
Total number of grades = 14
Number of A’s = 1 7.142 %
Number of B’s = 4 28.571 %
Number of C’s = 6 42.257 %
Number of D’s = 2 14.285 %
Number of F’s = 1 7. 142 %
The lowest grade is 50
The highest grade is 98
The average score is 75.5
I need to have variables that are needed in the loop and update them with each input value. After the loop do the calculations for percent, and average score.
