with predictable iteration order. This implementation differs from HashSet in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is
import java.util.*; public class TestMark_to_win { public static void main(String args[]) { HashSet h = new HashSet(); h.add("1"); h.add("2"); h.add("3"); h.add("4"); System.out.println(h); } }
A real-life usecase for HashSet can be storing data from stream where the stream may contain duplicate records, and we are only interested in distinct records. Another usecase can be finding distinct words in a given sentence. 7. Java HashSet Performance HashSet class offersconstant time perf...

For example, if an internal node has 3 child nodes (or subtrees) then it must have 2 keys: a1 and a2. All values in the leftmost subtree will be less than a1, all values in the middle subtree will be between a1 and a2, and all values in the rightmost subtree will be greater ...

In our previous article onHashSet internals, we have seen internal implementation of itsadd(),remove(),contains(),clear(),iterator()andisEmpty()methods. One of our readers has raised question aboutHow efficient is HashSet removeAll() method?As it requires detailed explanation, we have decided...
