System.out.print("\n"+"Please input a number:");
arrayList.add(new Integer(input()));
System.out.println("Current array'length:"+arrayList.size());
Object[] now=arrayList.toArray();
Arrays.sort(now);

}
}我在排序之前用了一个匿名类，这时候没有执行排序直接就加入然后输出了，这个才是正确程序，有点儿小区别；不好意思啊。。

问题是我不会怎么放到后面

嘀咕01
把输入的整数和原理的数字比较，放到小于原数组队后面就好了啊
