计算要放入数组元素中的值。

public class Main 

{

   public static void main(String[] args)//nowjava 提供

   {

      final int ARRAY_LENGTH = 10; // constant

      int[] array = new int[ARRAY_LENGTH]; // create array


      // calculate value for each array element

      for (int counter = 0; counter < array.length; counter++)

         array[counter] = 2 + 2 * counter;


      System.out.printf("%s%8s%n", "Index", "Value"); // column headings

   

      // output each array element's value
