List implementations are grouped into general-purpose and special-purpose implementations. There are two general-purpose List implementations — ArrayList and LinkedList. Most of the time, you'll probably use ArrayList, which offers constant-time positional access and is just plain fast.

Apr 8, 2025 · In a Java List, we can organize and manage the data sequentially. Key Features: Maintained the order of elements in which they are added. Allows duplicate elements. The implementation classes of the List interface are ArrayList, LinkedList, Stack, and Vector. It can add Null values that depend on the implementation.

In many implementations they will perform costly linear searches. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list.

Mar 7, 2025 · Learn about the Java list interface, including core functions and concrete implementations.

Jan 31, 2023 · In this article, you'll learn how to extend and implement the List interface in Java, and how to interact with elements in a collection. Here are the different implementation classes of the List interface in Java: AbstractList. AbstractSequentialList. ArrayList. AttributeList. CopyOnWriteArrayList. LinkedList. RoleList. RoleUnresolvedList. Stack.

In my program I often use collections to store lists of objects. Currently I use ArrayList to store objects. My question is: is this a best choice? May be its better to use LinkedList? Or something else? Criteria to consider are: Operations which I need are: Any thoughts?

Aug 22, 2024 · We‘ll cover the popular ArrayList and LinkedList, additional List implementations, detailed performance analysis, common errors and exceptions, and plenty of actionable insights for writing better Java code. Let‘s get started!

Feb 10, 2025 · In this Java list tutorial, I will help you understand the characteristics of list collections, how to use list implementations (ArrayList and LinkedList) in day-to-day programming and look at various examples of common programming practices when using lists.

In addition to the operations inherited from Collection, the List interface includes operations for the following: Positional access — manipulates elements based on their numerical position in the list. This includes methods such as get, set, add, addAll, and remove.

In Java, the List interface is an ordered collection that allows us to store and access elements sequentially. It extends the Collection interface. Since List is an interface, we cannot create objects from it. In order to use the functionalities of the List interface, we can use these classes:
