CASE_INSENSITIVE_ORDER是CaseInsensitiveComparator类的对象，这个类是String类的内部类，并且实现了Comparator接口。那再看看这个CaseInsensitiveComparator是怎么实现Comparator接口的compare方法的吧。如图中代码所示，对两个字符串进行比较时，会将字符串中的字符转换成统一的大小写进行比较，这样就达到了忽略大小写的功能。这...

compareToIgnoreCase()方法实现:String在内部自定义了一个名为CaseInsensitiveComparator的类,实现Comparator,用来比较忽略大小写的两个字符串,比较逻辑是,依次取出两个字符进行忽略大小写的比较,其余逻辑和上面类似。 hashCode()方法返回String的hash值。 3. startWith()、endWith() ...

public static final Comparator<String> CASE_INSENSITIVE_ORDER A Comparator that orders String objects as by compareToIgnoreCase. This comparator is serializable. Note that this Comparator does not take locale into account, and will result in an unsatisfactory ordering for certain locales. The java....
