使用通用方法printArray打印数组元素。

public class Main 

{/**来自 n o w j a   v  a . c o m - 时  代  Java**/

   public static void main(String[] args) 

   {

      // create arrays of Integer, Double and Character

      Integer[] integerArray = {1, 2, 3, 4, 5, 6};

      Double[] doubleArray = {1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7};

      Character[] characterArray = {'H', 'E', 'L', 'L', 'O'};


      System.out.print("Array integerArray contains:%n");

      printArray(integerArray); // pass an Integer array 

      System.out.printf("%nArray doubleArray contains:%n");

      printArray(doubleArray); // pass a Double array

      System.out.printf("%nArray characterArray contains:%n");

      printArray(characterArray); // pass a Character array
      /*
      n o w j a   v  a . c o m - 时  代  Java 提 供
      */

   } 


   // generic method printArray
