Write a program that computes the average of a set of grades. The user is prompted the following:
1-Number of grades to be entered.
2-The value of the minimum grade.
3-The value of the maximum grade.
Make sure to write input validation for the following:
1-The number of grades cannot be negative! In case it is 0, it means that user has no grades to enter.
2-Each entered grade should be a valid grade between the minimum and maximum values set by the user.
Finally, the program prints the average of the grades as show below:
note that the user only allowed to enter numbers as in image 4
line 12
when he entered "a" it shows an error message
We need at least 10 more requests to produce the answer.

Using Java, write a program that teachers can use to enter and calculate grades of individual students by utilizing an array, Scanner object, casting, and the print method. First, let the user choose the size for the integer array by using a Scanner object. The integer array will hold individual assignment grades of a fictional student. Next, use a loop to populate the integer array with individual grades. Make sure each individual grade entered by the user fills just one...
