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.
