![]() ![]() In detail, ArrayList and LinkedList represent two of the most widely adopted JVM data collection structures. This is why you should know the characteristics of each of the most popular data collections offered by the programming language you are using. Adopting the correct data collection can make all the difference when it comes to performance and resource usage. Also, thanks to its interoperability with the JVM, you can choose between the many Java collections. Kotlin provides several data collection implementations. ![]() ![]() Spreading knowledge through writing is my mission. We add elements using the add() method that the LinkedList class inherits from the Collection interface.Antonello Zanini Follow I'm a software engineer, but I prefer to call myself a technology bishop. How to add elements to LinkedList in Java? LinkedList inherits the same methods as ArrayList, so we use exactly the same methods to manipulate elements. Or using polymorphism. The variable that holds the address of the new object will be of type List. This is possible because LinkedList implements the List interface. ![]() LinkedList list = new LinkedList() Ä«etween the brackets, we specify which type of elements the list will contain. We create a new LinkedList object by instantiating it, just like any other class in Java.
