Scanner keyboard = new Scanner(System.in);

double[] score = new double[5];
int x;
double max;

System.out.println("Enter " + score.length + " scores: ");
score[0]=keyboard.nextDouble();

max = score[0];

for (x=1;x<score.length;x++)

{
score[x]=keyboard.nextDouble();

if(score[x]>max)
max=score[x];
}

System.out.println("highest score is " + score[x]);

}
}

literally can't figure out why

do you know how the for loop works? print out the x after you exit the loop. what do you expect x to be?

The for loop fails when x is 5. Outside of the loop you are trying to print score[5] which is out of bounds.

Edit

The highest score is also max not score[x]

iterate through that loop on paper


x = 1....< score.length(5)? true -> NEXT
x = 2....< score.length(5)? true -> NEXT
x = 3....< score.length(5)? true -> NEXT
x = 4....< score.length(5)? true -> NEXT
x = 5....< score.length(5)? FALSE -> EXIT LOOP

x is now 5

do you see now?


edit: slow to the trigger as usual
