Remove specified element from LinkedList Java example

This java example shows how to remove a particular element from Java LinkedList. It also shows how to remove an element at specified index from LinkedList.

import java.util.LinkedList;

public class RemoveElementLinkedListExample {

	public static void main(String[] args) {

		// create LinkedList object
		LinkedList lList = new LinkedList();

		// add elements to LinkedList
		lList.add("1");
		lList.add("2");
		lList.add("3");
		lList.add("4");
		lList.add("5");

		System.out.println("LinkedList contains : " + lList);

		/**
		 * To remove a specified element from Java LinkedList, use boolean
		 * remove(Object obj) method.
		 * 
		 * This method removes the first occurrence of the specified element
		 * from Java LinkedList and returns true if LinkedList contained the
		 * specified element.
		 * 
		 * If LinkedList did not contain the specified element, it remains
		 * unchanged.
		 **/

		boolean isRemoved = lList.remove("2");
		System.out.println("Is 2 removed from LinkedList ? :" + isRemoved);
		System.out.println("LinkedList now contains : " + lList);

		/**
		 * To remove an element at specified index of LinkedList, use Object
		 * remove(int index) method.
		 * 
		 * This method removes an element from specified index and shifts
		 * subsequent elements to the left. It returns an element previously at
		 * the specified index.
		 **/

		Object obj = lList.remove(2);
		System.out.println(obj + " has been removed from LinkedList");
		System.out.println("LinkedList now contains : " + lList);
	}
}

The output is:



LinkedList contains : [1, 2, 3, 4, 5]
Is 2 removed from LinkedList ? :true
LinkedList now contains : [1, 3, 4, 5]
4 has been removed from LinkedList
LinkedList now contains : [1, 3, 5]
