java中将一个list按照固定笔数平均分成若干个list

private static int batchSize = 3;
    public static void main(String[] args) {
        List<Integer> list = new ArrayList<>();
        for(int i = 1;i<=10;i++){
            list.add(i);
        }
        for(int i= 0;i < list.size() / batchSize;i++){
            List<Integer> insertList = list.subList(i*batchSize, (i+1)*batchSize);
            System.out.println(insertList);
        }
        if(list.size() % batchSize != 0){
            System.out.println("最后剩余的数据："+list.subList((list.size() / batchSize) * batchSize, list.size()));
        }else{
            System.out.println("正好整批处理成功");
        }
    }
