Difference between HashMap vs TreeMap vs LinkedHashMap in Java Hello guys, if you are wondering when to use HashMap, TreeMap and LinkedHashMap in Java and want to understand difference between them then you are at the right place. Earlier, I have shared difference between HashSet, TreeSet, and LinkedHashSet and in this article, I will explain the difference between these three common Map implementation HashMsp, TreeMap, and LinkedHashMap. Though all three classes like HashMap, LinkedHashMap and TreeMap are implementation of java.util.Map interface, there is some functional difference between them. Perhaps most notable difference between them comes from their iteration order. HashMap makes absolute no guarantee about in which order you can iterate their keys, any application depending upon iteration order of HashMap is fragile, because it can change anytime. In fact, in Java 7, iteration order of HashMap is different than Java 6. Java Interview questions and tutorials Read: http://www.java67.com/2022/05/hashmap-vs-treemap-vs-linkedhashmap-in.html
