Create an object array from elements of LinkedList in Java

Java 8Object Oriented ProgrammingProgramming

An object array can be created from the elements of a LinkedList using the method java.util.LinkedList.toArray(). This method returns the object array with all the LinkedList elements in the correct order.

A program that demonstrates this is given as follows.

Example

 Live Demo

import java.util.LinkedList;
public class Demo {
   public static void main(String[] args) {
      LinkedList<String> l = new LinkedList<String>();
      l.add("Amy");
      l.add("Sara");
      l.add("Joe");
      l.add("Betty");
      l.add("Nathan");
      Object[] objArr = l.toArray();
      System.out.println("The object array elements are: ");
      for (Object i: objArr) {
         System.out.println(i);
      }
   }
}

Output

The output of the above program is as follows −

The object array elements are:
Amy
Sara
Joe
Betty
Nathan

Now let us understand the above program.

The LinkedList l is created. Then LinkedList.add() is used to add the elements to the LinkedList. A code snippet which demonstrates this is as follows

LinkedList<String> l = new LinkedList<String>();
   
l.add("Amy");
l.add("Sara");
l.add("Joe");
l.add("Betty");
l.add("Nathan");

The LinkedList.toArray()method is used to convert the LinkedList into an object array objArr[]. Then the object array is displayed using a for loop. A code snippet which demonstrates this is as follows

Object[] objArr = l.toArray();
   
System.out.println("The object array elements are: ");

for (Object i: objArr) {
   System.out.println(i);
}
