1. Use TreeMapThe HashMap in Java provides good performance but doesn’t maintain any order of its elements. If you want insertion-order iteration with near-HashMap performance, you can use LinkedHashMap. If you want sorted-order iteration, you can use the TreeMap implementation of the Map...
A linked list is adata structurethat consists of a sequence of nodes, where each node stores an element and a reference to the next node. In Java, theLinkedListclass implementstheIterableinterface, which provides several ways toiteratethrough its elements. In this article, we will discuss three ...
