Java LinkedList remove() Method

❮ LinkedList Methods

import java.util.LinkedList;

public class Main { 
  public static void main(String[] args) { 
    LinkedList<String> cars = new LinkedList<String>();
    cars.add("Volvo");
    cars.add("BMW");
    cars.add("Ford");
    cars.add("Mazda");
    cars.remove(0);
    System.out.println(cars);
  } 
}

Definition and Usage

The remove() method removes an item from the list, either by position or by value. If a position is specified then this method returns the removed item. If a value is specified then it returns true if the value was found and false otherwise.

If a value is specified and multiple elements in the list have the same value then only the first one is deleted.

If the list contains integers and you want to delete an integer based on its value you will need to pass an Integer object. See More Examples below for an example.

Syntax

One of the following:

public T remove(int index)

public boolean remove(Object item)

T refers to the data type of items in the list.
