（Integer[]）array；

        Object[] os = new Object[] { 1, 2, 3 };
        Integer[] is = Arrays.asList(os).toArray(new Integer[0]);

------解决方案--------------------
当然不行，程序会抛出can't cast的错误！

------解决方案--------------------
这样可以
   public static void main(String[] args) {
   	Integer[] a = {1,2,3,4,5,6};
   	Object[] o = a;
   	Integer[] b= (Integer[])o;
   	System.out.println(Arrays.toString(b));
   }

Java code

Object[] os = new Object[] { 1, 2, 3 };
Integer[] is = Arrays.asList(os).toArray(new Integer[0]);
