一组数字的平均值是它们的总和除以数量。可以定义为-
average = sum of all values / number of values
在这里,我们将学习如何以编程方式计算平均值。
1. Collect integer values in an array A of size N. 2. Add all values of A. 3. Divide the output of Step 2 with N. 4. Display the output of Step 3 as average.
public class AverageOfNNumbers { public static void main(String args[]){ int i,total; int a[] = {0,6,9,2,7}; int n = 5; total = 0; for(i=0; i<n; i++) { total += a[i]; } System.out.println("Average ::"+ total/(float)n); } }
输出结果
Average ::4.8
