List to array in Java

Given a List (LinkedListor ArrayList) of strings in Java, convert it into an array of strings.

Method 1 (Simple using get())

We can use below list method to get all elements one by one and insert into an array.

// Returns the element at the specified index in the list.
public E get(int index)

// using get() in a loop.
import java.io.*;
import java.util.List;
import java.util.LinkedList;
  
class GFG
{
    public static void main (String[] args)
    {
        List<String> list = new LinkedList<String>();
        list.add("Geeks");
        list.add("for");
        list.add("Geeks");
        list.add("Practice");
  
        String[] arr = new String[list.size()];
  
        // ArrayList to Array Conversion
        for (int i =0; i < list.size(); i++)
            arr[i] = list.get(i);
  
        for (String x : arr)
            System.out.print(x + " ");
    }
}

                        filter_none









Output:


Geeks for Geeks Practice





 Method 2 (Using toArray) 











                                    filter_none

 Method 3 (Using Stream) 











                                    filter_none

// Set to array using stream 


import java.util.*; 


  


class Test { 


    public static void main(String[] args) 


    { 


        List<String> list = new LinkedList<String>(); 


        list.add("Geeks"); 


        list.add("for"); 


        list.add("Geeks"); 


        list.add("Practice"); 


  


        int n = list.size(); 


        String[] arr = list.stream().toArray(String[] ::new); 


        for (String x : arr) 


            System.out.print(x + " "); 


    }
