TheString.CASE_INSENSITIVE_ORDERgives back aComparatorthat compares two Strings by ignoring their case. As the case of the keys will be ignored, we will only find one entry in the Map. Map<String,Integer>caseInsensitiveTreeMap=newTreeMap<>(String.CASE_INSENSITIVE_ORDER);caseInsensitiveTreeMap.p...

String.CASE_INSENSITIVE_ORDER。 2.Set排序 Java对于Set有按照自然顺序排列的实现类,TreeSet,对这个TreeSet对象的引用进行操作就行了,自己就是排好序的。当然,TreeSet也提供了多个构造方法,尤其是接收Comparator类型参数的构造方法,允许开发者按照自己的想法进行排序,而不仅是局限于自然排序。
