import java.util.ArrayList;
import java.util.Arrays;

public class ArrayListToStringArray {

    public static void main(String args[]){

        //ArrayList containing string objects
        ArrayList<String> nameList = new ArrayList<String>();
        nameList.add("Max");
        nameList.add("Tom");
        nameList.add("John");

                /*
                 * To convert ArrayList containing String elements to String array, use
                 * Object[] toArray() method of ArrayList class.
                 *
                 * Please note that toArray method returns Object array, not String array.
                 */

        //First Step: convert ArrayList to an Object array.
        Object[] objNames = nameList.toArray();

        //Second Step: convert Object array to String array

        String[] strNames = Arrays.copyOf(objNames, objNames.length, String[].class);

        System.out.println("ArrayList converted to String array");

        //print elements of String array
        for(int i=0; i < strNames.length; i++){
            System.out.println(strNames[i]);
        }
    }
}

/*
Output:
ArrayList converted to String array
Max
Tom
John
*/
