Choosing the Right Set Implementation for Your Needs in Java
We explored ArrayList
and LinkedList
in the previous article. So it became necessary to compare set implementations. When it comes to storing a collection of unique elements, two popular choices are HashSet
and TreeSet
. Both of these implementations belong to the java.util
package and offer distinct characteristics, advantages, and use cases. In this article, we will explore HashSet
and TreeSet
, moreover try to help you make informed decisions when choosing the proper set implementation for specific requirements of your application.
