It does not give access to the null element. 1 1 asked Feb 5, 2016 at 12:27 Sabir Khan 9,756 7 43 98 2 Look at the source code for TreeMap.getEntry, which TreeSet.get uses. When we create an object of TreeSet without any comparator(default constructor of TreeSet), it internally creates an object of TreeMap and TreeMap assign comparator is null. What's the logic behind macOS Ventura having 6 folders which appear to be named Mail in ~/Library/Containers? You will be notified via email once the article is available for improvement. The Spliterator reports Spliterator.SIZED, from, Returns a view of the portion of this set whose elements are Overriding implementations should document When you are willing to trade off slightly higher memory usage for the benefits of automatic sorting and range operations. The put method checks if the object of the comparator is null then it compares the element based on comparable. It will get a shallow copy of this TreeSet instance. set.add("AA"); set.add(20); add at a random spot in the memory and linked to the element before it and after it ? the given element, or, Returns a view of the portion of this set whose elements are This is best done at creation time, to prevent accidental Returns the number of elements in this set (its cardinality). Returns an iterator over the elements in this set in descending order. boolean addAll(Collection
