This is a gradebook that is suposed receive so many grades and I'm having a hard time getting the high grade, low grade and average, I also need the Letter grade from the average. Can you please help:/

for(outercounter = 0; outercounter<name.length; outercounter++ ){
System.out.print("Enter the students name: ");
String studentName = input.next();
name[outercounter]=studentName;

int grade = input.nextInt();
gradebook[outercounter][innercounter]=grade;
