java数组使用 四 反转数组元素

package array;

public class Demo04 {

   final static int[] arrays = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};

   public static void main(String[] args) {
       printArray(arrays);

       int[] reverse = reverse(arrays);
       System.out.println(reverse);//[I@1b6d3586
       printArray(reverse);//10	9	8	7	6	5	4	3	2	1
   }

   //    打印所有
   public static void printArray(int[] arrays) {
       for (int array : arrays) {
           System.out.print(array + "\t");// 1	   2	3	4	5	6	7	8	9	10
       }
       System.out.println();
   }

   //    反转数组
   public static int[] reverse(int[] arrays) {
       int[] result = new int[arrays.length];

       for (int i = 0, j = result.length - 1; i < arrays.length; i++, j--) {
           result[j] = arrays[i];
       }
       return result;
   }

}

运行结果
