LinkedHashSet]:1,2,3,4,5,10 List[java.util. More specifically, it uses a java.util.HashMap to store the hashes and elements and to prevent duplicates. In contrast, the LinkedHashSet class is similar to the HashSet. Introduction to Java LinkedHashSet With Examples LinkedHashset Arraylist vs LinkedList vs LinkedHashSet Summary. Checking if an element exists in the set will be more efficient. 1. 1. In Java Set (I) stores unique elements.
