Java排序列表列表

您将必须实现自己的

Comparator

Collections.sort()

class ListComparator<T extends Comparable<T>> implements Comparator<List<T>> {  @Override  public int compare(List<T> o1, List<T> o2) {    for (int i = 0; i < Math.min(o1.size(), o2.size()); i++) {      int c = o1.get(i).compareTo(o2.get(i));      if (c != 0) {        return c;      }    }    return Integer.compare(o1.size(), o2.size());  }}

然后分类很容易

List<List<Integer>> listOfLists = ...;Collections.sort(listOfLists, new ListComparator<>());
