Question

Complete the attached program to input grades until a negative number is input, then to print out the average of the grades.

Do not change anything in the main method. Just define two methods, the input method and the average method, as described in the comments in the attached file.

Sample run:

Enter a grade, negative to quit: 97
Enter a grade, negative to quit: 95
Enter a grade, negative to quit: 96
Enter a grade, negative to quit: 57
Enter a grade, negative to quit: 91
Enter a grade, negative to quit: -1
97.0, 95.0, 96.0, 57.0, 91.0
Your average is 87.2

/* The input method takes an array of

/* The average method takes an array of

average of the grades as a double.

public static void main(String[] args) {
double[] grade = new double[100];
int gradeCount = input(grade);
//Print all grades but the last one
with a comma after.
for (int i=0; i<gradeCount-1; i++) {
System.out.print(grade[i] + ", ");
}
//Print the last one without a comma
and go to the next line.
II
System.out.println(grade[gradeCount-1]);
//Print the average using the average
method, rounded to the nearest tenth.
System.out.printf("Your average is
%.1f%n", average(grade, gradeCount));
}
