In this section, we will discuss some of the important points about Java Set: Java Set interface is a member of the Java Collections Framework. ConcurrentSkipListSet is a thread-safe Set with its elements sorted according to their natural ordering, or by a Comparator provided at set creation time, depending on which constructor is used.

Insertion, removal, and access Constructs a new, empty set that orders its elements according to Removes the specified element from this set if it is present. Since it implements SortedSet and NavigableSet, it is similar to TreeSet with an added feature of being concurrent. As we can see, we achieve similar performance to Java, with some minor differences. The descending set is backed by this set, so changes to the set are ConcurrentSkipListSet in Java is a sorted set just like TreeSet but it is also scalable and concurrent so ConcurrentSkipListSet is thread-safe and can be accessed by multiple threads safely.

Answer (1 of 3): Use a java.util.TreeSet or a java.util.concurrent.ConcurrentSkipListSet TreeSet (Java Platform SE 8 ) and ConcurrentSkipListSet (Java Platform SE 8 ) From the description of TreeSet: > A NavigableSet implementation based on a TreeMap. Contains the collections framework, some internationalization support classes, a service loader, properties, random number generation, string parsing and scanning classes, base64 encoding and decoding, a bit array, and several miscellaneous utility classes. Returns a possibly parallel Stream with this collection as its source. Since it is a thread-safe, it can be used by multiple threads concurrently whereas TreeSet is not thread-safe. Constructs a new, empty set that orders its elements according to Unlike List, Set DOES NOT allow you to add duplicate elements. The ConcurrentSkipListSet class in Java is a part of the Java Collection Framework and implements the Collection interface and the AbstractSet class.It provides a scalable and concurrent version of NavigableSet in Java.The implementation of ConcurrentSkipListSet is based on ConcurrentSkipListMap.The elements in ConcurrentSkipListSet are sorted by default in their natural ordering or by a .
