I want to get a 5 day moving average from an array of numbers like so.
Array of numbers: 11,12,13,14,15,16,17
First day of 5-day moving average: (11 + 12 + 13 + 14 + 15) / 5 = 13
Second day of 5-day moving average: (12 + 13 + 14 + 15 + 16) / 5 = 14
Third day of 5-day moving average: (13 + 14 + 15 + 16 + 17) / 5 = 15
int[] arry = {11,12,13,14,15,16,17};
int sum = 0;
for(int j = 0; j < 5; j++) {
sum += arry[j];
System.out.println(sum);
}
System.out.println();
int average = sum / 5;
System.out.println("Sum: " + sum);
System.out.println("Average: " + average);
Am able to get the first average but am lost on how to implement a loop to get the next set of averages?
Please see the following tested code (method from @ajb is more elegant, but I use the idea from @zapl for simplicity):
public static void main(String[] args) {
int[] arry = { 11, 12, 13, 14, 15, 16, 17 };
int size = 5;
for (int i = 0; i + size <= arry.length ; i++)
int sum = 0;
for (int j = i; j < i + size; j++) {
sum += arry[j];
System.out.println(sum);
}
System.out.println();
int average = sum / 5;
System.out.println("Sum: " + sum);
System.out.println("Average: " + average);
}
}
