Java 程序用来计算 Java 中数字的平均值
一系列数字的平均值是它们之和除以它们的个数。 它可以定义为 -
average = sum of all values / number of values
这里我们将学习如何以编程方式计算平均值。
算法
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.
示例
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); } }
