TreeSet maintains objects in sorted order. Sample Java code to demonstrate HashSet and TreeSet public class HashSetAndTreeSet { static public void main(String[] args) { HashSet<String> hashSet = new HashSet<String>(); // add elements to HashSet hashSet.add("Sachin"); hashSet.add("Vi...
speaking, impossible to make any hard guarantees in the presence of unsynchronized concurrent modification. Fail-fast iterators throw ConcurrentModificationException on a best-effort basis. Therefore, it would be wrong to write a program that depended on this exception for its correctness: the fail-fa...

Why NULL is Not Allowed in Java TreeSet? TreeSet是 Java 中SortedSet 接口最重要的实现之一,它使用树进行存储。无论是否提供显式比较器,元素的顺序都由使用其自然顺序的集合维护。这必须和equals一致才能正确实现Set接口。 例子: Java实现 // Java Program to illustrate the TreeSet ...
