The LinkedHashMap class in Kotlin is part of the kotlin.collections package. It combines the features of a HashMap with a linked list, allowing for predictable iteration order. This class offers a variety of functions to manage and manipulate the entries in the map.
This guide covers various functions available in the Kotlin LinkedHashMap class. Each function is described in simple terms to help beginners understand how to use them. These functions enable you to perform operations such as adding, removing, and querying entries in the map.
