Following methods are used to remove element from linkedlist in java:
- remove(): It retrieves and removes the first element of the list.
- remove(index): It removes the element at the specified position in the list.
- remove(object): It removes the first occurrence of the specified element from the list, if it is present.
- removeFirst(): It removes and returns the first element from the list.
- removeFirstOccurrence(object): It removes the first occurrence of the specified element in the list (when traversing the list from head to tail).
- removeLast(): It removes and returns the last element from the list.
- removeLastOccurrence(object): It removes the last occurrence of the specified element in the list (when traversing the list from head to tail).
Example:
package com.w3spoint; import java.util.LinkedList; public class Test { public static void main(String args[]){ LinkedList<String> linkedList = new LinkedList<String>(); linkedList.add("Jai"); linkedList.add("Mahesh"); linkedList.add("Naren"); linkedList.add("Vivek"); linkedList.add("Vishal"); linkedList.add("Hemant"); System.out.println("Actual LinkedList:"+linkedList); System.out.println("remov() method:"+linkedList.remove()); System.out.println("After remove() method call:"); System.out.println(linkedList); System.out.println("remove(index) method:"+linkedList.remove(2)); System.out.println("After remove(index) method call:"); System.out.println(linkedList); System.out.println("remov(object) method:"+linkedList.remove("Hemant")); System.out.println("After remove(object) method call:" + linkedList); } } |
Output
Actual LinkedList:[Jai, Mahesh, Naren, Vivek, Vishal, Hemant] remov() method:Jai After remove() method call: [Mahesh, Naren, Vivek, Vishal, Hemant] remove(index) method:Vivek After remove(index) method call: [Mahesh, Naren, Vishal, Hemant] remov(object) method:true After remove(object) method call:[Mahesh, Naren, Vishal] |
