#LINKEDLIST VS ARRAY VS ARRAYLIST CODE#

So the question we are going to try to answer is, which is better: ArrayList or LinkedList?Д«ut before we discuss which implementation is better I would like to state that you should always avoid declaring a variable or a method as one of these types and instead use an interface. But the performance of some operations will vary depending on the type of list you use.

#LINKEDLIST VS ARRAY VS ARRAYLIST CODE#

There are several types that implement the List interface, but the most used are ArrayList and LinkedList.ДЄs both implement the same interface they do basically the same things, so for most of the cases your code will work whichever implementation you use. This means that we are able to access an element inside a List by its position (index). A list is an ordered collection of elements which controls where in the list each element is inserted. One of the most used interface on the Collections framework is the List. In other words we write decoupled code, which is really good, especially when you have to make changes to your application.ДЄnother good thing about the interfaces defined in the framework is that they are generic вЂ“ so we can instantiate a collection of any type we need (even a collection of collections). This framework defines lots of interfaces and classes for grouping objects and performing manipulations on groups such as insert, delete, sort and many more.Д«y using the interfaces provided we can write code less dependent of the implementation of the elements. As you probably know, Java provides a comprehensive Collections framework.
