LinkedList remove() Method in Java

In Java, the remove() method of the LinkedList class removes an element from the list, either by specifying its index or by providing its value.

Example 1: Here, we use the remove() method to remove element from the LinkedList of Strings. By default the remove() will remove the beginning element(head) of the list.

[Geeks, for, Geeks]
[for, Geeks]

Illustration:

Now there are two versions of the remove() method i.e. remove an element by index and remove an element by value.

1. Remove an Element by Index

Syntax:

E remove(int index)

• Parameter: Index is the position of the element we want to remove from the list.
• Return Type: This method return the element that was removed from the list.

Example 2: Here, we use the remove() method to remove the element at the specified index from the list.

[A, B, C, D, E]
Removed Element: B
[A, C, D, E]

2. Remove an Element by Value

Syntax:

boolean remove(Object item)

Parameter: item - It is the element we want to delete from the LinkedList.

Return Type: This method will return a boolean value.

• It will return true, if the specified element is removed form the list
• It will return false, if the specified element is not found in the list.

Example 3: Here, we use the remove() method to remove any specified element from the LinkedList.
