LinkedList
Convert LinkedList to Object array example
This is an example of how to convert a LinkedList to an Object array. Converting a LinkedList to an array implies that you should:
- Create a new LinkedList.
- Populate the list with elements, with
add(E e)
API method of LinkedList. - Get an array containing all of the elements in this list in proper sequence (from first to last element), using
toArray()
API method of LinkedList. - Note that no references to the returned array are maintained by this list. The caller is thus free to modify the returned array.
Let’s take a look at the code snippet that follows:
package com.javacodegeeks.snippets.core; import java.util.LinkedList; public class LinkedListToArray { public static void main(String[] args) { // Create a LinkedList and populate it with elements LinkedList linkedList = new LinkedList(); linkedList.add("element_1"); linkedList.add("element_2"); linkedList.add("element_3"); linkedList.add("element_4"); linkedList.add("element_5"); // Object[] toArray() method returns an array containing all of the elements in this set Object[] objArray = linkedList.toArray(); System.out.println("Elements in Array :"); for(int i=0; i < objArray.length ; i++) System.out.println(objArray[i]); } }
Output:
Elements in Array :
element_1
element_2
element_3
element_4
element_5
This was an example of how to convert a LinkedList to an Object array in Java.
