Thread: Brand-new to Java please help with project!

I am working on a project for my intro class and have hit a wall. This is my first time doing this sort of thing so please be gentle

It goes as follows:

For this project, you will create a Java application that accepts a student’s class grades from the keyboard; calculates the average grade as a percentage for each grading category; and then calculates the overall grade as both a percentage and a letter grade. The program then creates a grade report on the console showing both detail and aggregate information.

The program prompts the user for the student’s name and stores that information in memory.
The application inputs scores from the user in four grading categories--quizzes, in-class assignments, homework assignments and attendance--and stores that information in memory. You may choose to use objects of a class you create to store the score information.
The application may prompt the user for this information using the console or a message dialog box.
The prompt to the user for each score will indicate both the category of the score and a unique identifier for the score, e.g. “Quiz 3” or “Attendance 9/29/2018.”
The program displays a report on the console with an appropriate title showing the student’s name that was entered by the user and the details of each grade entered:
grade category (quiz, in-class assignment, homework or attendance)
score name (e.g. “Quiz 3” or “Homework 4”)
points earned
points possible
The program displays on the report the average score, as a percentage, for each grading category and labels each clearly. Where you choose to display all the elements on the report is up to you. Just remember readability is important.
Attendance is worth 1 point per day and counts for 20% of the total grade. Create six attendance scores from user input.
Quizzes are 10 points each and count for 20% of the total grade. Create six quiz scores from user input.
In-class assignments are 10 points each and count for 20% of the total grade. Create six in-class assignment scores from user input.
Homework assignments are 20 points each and count for 40% of the total grade. Create six homework assignment scores from user input.
The report displays an overall grade as both a percentage and as a letter grade. Use the following ranges to determine the letter grade.
A

90 through 100

B

80 to < 90

C

70 to < 80

D

60 to < 70

F

< 60

So... (for what it's worth) here is what I have come up with so far...

}

Any help would be greatly appreciated!

I have, through trial and error, gotten the code to run, now I am just fixing formatting issues. Please stay tuned as I am sure I will have more problems. It was pasted from a .txt file which makes the formatting look worse than it really is in the ide.

Ok, here is the nightmare I have come up with. The last step it seems, would be to then convert the student's percentage grade into a letter grade. I have no idea where to start. Can someone steer me in the right direction?

Thank you
