#Steps:

Create a Main class.
Declare an ArrayList in the main() method and store the given values in it.
Create an array called output of the size of the ArrayList.
Iterate through for-loop to get each element from the array List and load it into the array using the get() method of the list.
Print the array to see the loaded elements.

import java.util.ArrayList;

import java.util.List;

public class Main {

public static void main(String[] args) {

List<String> nameList = new ArrayList<String>();

nameList.add("Robert");

nameList.add("Samson");

nameList.add("Alex");

nameList.add("William");

System.out.println("Elements of List: " + nameList);

// Create an array of the same size as nameList Hint: use size() method

// Fetch the elements from the nameList and insert into newly created array

// Hint: Use get() method to fetch the elements from arraylist and use for loop

System.out.print("Elements of Array: ");

for (int i = 0 ; i < output.length ; i++){

System.out.print(output[i] + " ");

}
