Java LinkedList - remove() Method

The java.util.LinkedList.remove() method is used to remove the element at the specified position in the list. It shifts any subsequent elements to the left by subtracting one from their indices. Every removal of element results into reducing the list size by one unless the list is empty.

Syntax

public E remove(int index)

Here, E is the type of element maintained by the container.

Parameters

Return Value

Returns the removed element of the list.

Exception

Throws IndexOutOfBoundsException, if the index is out of range (index < 0 || index >= size()).

Example:

In the example below, the java.util.LinkedList.remove() method is used to remove the element at the specified position in given list.

import java.util.*;

public class MyClass {
  public static void main(String[] args) {
    //creating a linkedlist
    LinkedList<Integer> MyList = new LinkedList<Integer>();

    //populating linkedlist 
    MyList.add(10);
    MyList.add(20);
    MyList.add(30);
    MyList.add(40);

    //printing linkedlist
    System.out.println("MyList contains: "+ MyList);    

    //delete element at index=2
    MyList.remove(2);

    //printing linkedlist
    System.out.println("MyList contains: "+ MyList);  
  }
}

The output of the above code will be:

MyList contains: [10, 20, 30, 40]
MyList contains: [10, 20, 40]
