please help java

In this hw, you are asked to write a Java program that loads a series of integers one by one (scores obtained by students in a test) and prints a report showing the following: 1) How many students passed the test (passing a test is obtaining a score of 70 or higher) 2) Print a report like the one shown in the sample run, a report that shows how many received the grade of A,B,C,D and F. The standard letter grade scale is used-See sample run. Note Well that you are NOT allowed to use arrays, arraylists, or any data structures that allow holding more than one value. That is: All variables declared in your code must be single variables declared from the primitive data types (or strings). Welcome to my program. You will be asked to enter the scores of a test one by one, and to enter 1 to stop. Enter Score (Enter 1 to Stop): 78 Enter Score (Enter 1 to Stop): 96 Enter Score (Enter 1 to Stop): 45 Enter Score (Enter 1 to Stop): 78 Enter Score (Enter 1 to Stop): 69 Enter Score (Enter - 1 to Stop): 71 Enter Score (Enter - 1 to Stop): 771 Score 771 Rejected Enter Score (Enter 1 to Stop): 47 Enter Score (Enter - 1 to Stop): 67 Enter Score (Enter 1 to Stop): 82 Enter Score (Enter 1 to Stop): 458 Score 458 Rejected Enter Score (Enter - 1 to Stop): 100 Enter Score (Enter 1 to Stop): 17 Enter Score (Enter - 1 to Stop): 97 Enter Score (Enter 1 to Stop): 1 Here is your report: A total of 12 scores entered. 7 of them are 70 or higher. Letter Grade distribution of the scores: 3 Students earned the grade of A (90-100) 1 Students earned the grade of B (80-89) 3 Students earned the grade of C(7079) 2 Students earned the grade of D (60-69) 3 Students earned the grade of 7 ( 59 or below) The average score is: 70.58 Would you like to process another class?
