Problem statement

In this program, we will create a list using the LinkedList collection with some elements. Then we will convert the LinkedList collection into the array and print the array.

Java program to convert a LinkedList collection to an array

The source code to convert a LinkedList collection to an array is given below. The given program is compiled and executed successfully.

// Java program to convert a LinkedList 
// collection to an array

import java.util.*;

public class Main {
  public static void main(String[] args) {
    LinkedList < Integer > list = new LinkedList < Integer > ();

    list.add(1);
    list.add(2);
    list.add(3);
    list.add(4);
    list.add(5);

    Object[] arr = list.toArray();
    System.out.println("Array: \n" + Arrays.toString(arr));
  }
}

Output

Array: 
[1, 2, 3, 4, 5]

Explanation

In the above program, we imported the "java.util.LinkedList" package to use the LinkedList collection class. Here, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

In the main() method, we created a list using the LinkedList collection and added items using add() method. Then we converted the LinkedList collection to an array using the toArray() method and printed the returned array.
