Java如何使用locale对字段进行排序？

Question

我正在尝试按具有特定区域设置的字段对列表进行排序。我如何结合以下陈述？

names.stream().sorted(Comparator.comparing(AClass::getName)).collect(Collectors.toList());

Collator coll = Collator.getInstance(new Locale("tr","TR"));
coll.setStrength(Collator.PRIMARY);

Answer 1

有Comparator.comparing的变体带有两个参数。第二个参数是比较器，因此您可以将Collator实例作为第二个参数传递：

Collator coll = Collator.getInstance(new Locale("tr","TR"));
coll.setStrength(Collator.PRIMARY);
List<AClass> sorted = names.stream()
                           .sorted(Comparator.comparing(AClass::getName,coll))
                           .collect(Collectors.toList());

Answer 2

    List<Model> sortedModelList = unSortedModelList.stream()
    .sorted(Comparator.comparing(Model::getField,Collator.getInstance(new Locale("tr","TR"))))
.collect(Collectors.toList());
