java中数组元素位移（效率较高）

System.arraycopy(array,index[下标],array,index+1[位移的位置],size-index[位移元素的个数])

 public static void c() {
        String[] array = {"aa", "bb", "cc", "dd", "ee"};
        System.out.println(Arrays.toString(array));
        System.arraycopy(array, 1, array, 2, 3);
        System.out.println(Arrays.toString(array));
    }

    public static void main(String[] args) {
        c();
    }
