Java中将List拆分为多个小list集合的实现代码

public static <T> List<List<T>> splistList(List<T> list,int subNum) {
    List<List<T>> tNewList = new ArrayList<List<T>>();
    int priIndex = 0;
    int lastPriIndex = 0;
    int insertTimes = list.size()/subNum;
    List<T> subList = new ArrayList<>();
    for (int i = 0;i <= insertTimes;i++) {
      priIndex = subNum*i;
      lastPriIndex = priIndex + subNum;
      if (i == insertTimes) {
        subList = list.subList(priIndex,list.size());
      } else {
        subList = list.subList(priIndex,lastPriIndex);
      }
      if (subList.size() > 0) {
        tNewList.add(subList);
      }
    }
    return tNewList;
  }

public static void main(String[] args) {
    List<String> list = Arrays.asList("1","2","3","4","5","6","7","8","9");
    List<List<String>> lists = splistList(list, 4);
    System.out.println(lists.size());
  }
