In this article we are gonna discuss the differences betweenHashSetandHashMapclasses. HashSet vs HashMap Differences: Similarities: 1) Both HashMap and HashSet are not synchronized which means they are not suitable for thread-safe operations unitl unless synchronized explicitly. This is how you c...
LinkedHashSetis in some sense intermediate between HashSet and TreeSet. Implemented as aHashTablewith a linked list running through it, however it provides insertion-ordered iteration which is not same as sorted traversal guaranteed by TreeSet. So choice of usage depends entirely on your needs bu...
