Thread: Help with Average and Variables Please =)

I wanna add:
system print of the average of all the scores that were entered.
and a system print of the maximum of all the scores that were entered.

Can anyone help me and add that in there? ive been trying for hours, even bought a java book. couldnt figure it out haha. And if they could explain what you did thanks!

public static void main(String[] args) {
        // TODO code application logic here
     String fName = null;
     int count = 0; 
 
 
 
 
Scanner scan = new Scanner(System.in);
 
while ( fName != "stop" ) {
System.out.println("Enter the user's score from 0 to 100 ");
System.out.println("....or you can always enter STOP to quit the app.");
System.out.println("So far you have entered only " + count + " grades.");
System.out.print("\nINPUT: ");
int score = scan.nextInt();
 
count++;
 
if (score >= 101) {
System.out.println("Too high!");
 
else
 
 
switch(score / 10)
  {
  case 10:
  case 9: System.out.println("Letter grade is A\n");
  break;
  case 8: System.out.println("Letter grade is B\n");
  break;
  case 7: System.out.println("Letter grade is C\n");
  break;
  case 6: System.out.println("Letter grade is D\n");
  break;
  default: System.out.println("Letter grade is F\n");
}
    }
  }
}

If you want to figure out the average. First know the formula.. Surely you know this (sum of values / # of values).. I'm sure you can go from there.. (if you wrote this code on your own)

G'luck, comment back if you have any questions.

Well, you have the variables switched around.. It would be this

int average = scoreSum/count

In order to get the Sum of the Scores, you have to add them to a variable each time you get a score in.
So basically, here's the logic:
I have a count variable of length (let's make something up) 5.
Therefore, I must have 5 scores.
If I want to get the average, I must find the sum of the scores.
The score variable changes every time I run my loop, so simply multiplying the score by 5 at the end won't work.
So in all, I must find a way that I can add each individual score to "something" 5 times... You can go from here, it's best to learn from Trial & Error


And if you want to display the maximum grade, you have to have a variable that changes every time a higher number comes..
This concept is a little harder, but first, try to get the Average section working.
