Hi,

I'm wondering how PriorityQueue works with natural order of String. Does it use hashcode of String to determine the order?
anyone knows answer to this? please

thank you

No, not the hashcode. That wouldn't give the natural order of String, which is simply alphabetical, or really lexicographical. It uses the String.compareTo(String) method. You can give the PriorityQueue a different Comparator to use if you want, say, a case-insensitive sorting.
