This all java

Create a small JAVA program that calculates the final grade for a course. The program should include all these and at the end print the letter grade. Also, a while loop incases the user inputs invalid characters.

Five assignments worth 30 points each.

Three projects worth 100 points each.

Seven quizzes worth 20 points each.

Participation is worth 10 points.

Your final grade is calculated out of the total points you earn. For example, if the total possible points are 500 and you have a 461, your grade is 461/500 x 100 = 92% which is an A-.
