To convert an array into a java.util.LinkedList we can use the java.util.Arrays class’s asList() method. The Arrays class in the java.util package provides a utility method to convert an array to a List. The Arrays.asList() method will convert an array to a fixed size List. To create a LinkedList, we just need to pass the List to the constructor of the java.util.LinkedList class. A java.util.ArrayList could be created in this way too.
The Code
The following code example demonstrates converting an Array of Strings to a LinkedList of Strings.

import java.util.Arrays; import java.util.Iterator; import java.util.LinkedList; /** * Java 1.4+ Compatible * The following example code demonstrates converting an Array of Strings to a LinkedList of Strings */ public class Array2LinkedList { public static void main(String[] args) { // initialize array with some data String[] sa = new String[] { "A", "B", "C" }; // convert array to LinkedList LinkedList ll = new LinkedList(Arrays.asList(sa)); // iterate over each element in LinkedList and show what is in the list. Iterator iterator = ll.iterator(); while (iterator.hasNext()) { // Print element to console System.out.println((String) iterator.next()); } } } |
Result
Here is the output of the above example code showing how to convert an Array of Strings to a LinkedList of Strings.
