一个List 根据参数 拆分成多个list 的实现

废话不多说直接上代码：

public class domeTest2 {

    public static void main(String[] args) {
        List<List<String>> list =    domeTest2.subList(Arrays.asList("a","b","c","d","e"),3);
        System.out.println(list);
    }


    private static <T> List<List<T>> subList(List<T> list, int groupNum){
        int size = list.size();
        int temp = size / groupNum + 1;
        boolean special = size % groupNum == 0;
        List<List<T>> resultList = new ArrayList<>();
        for (int j = 0; j < temp; j++) {
            List<T> insertList=null;
            if (j == temp - 1) {
                if (special) {
                    break;
                }
                insertList = list.subList(groupNum * j, size);
            } else {
                insertList = list.subList(groupNum * j, groupNum * (j + 1));
            }
            resultList.add(insertList);
        }
        return resultList;
    }
}

返回值：
