对集合对象进行排序:根据对象集合其中一属性进行排序

private List<String> getSettlementCodeSort(List<String> stringList,int currentPage,int pageSize){Collections.sort(stringList, Comparator.reverseOrder());//根据String类型属性倒序ArrayList<Person> personlist = new ArrayList<>();stringList.sort((a,b)->a.getName().compareTo(b.getName()));//根据集合中name属性正序Collections.sort(personlist , (a,b)->{//根据集合中age属性正序return a.getAge() - b.getAge();});}
