Convert a List (ArrayList) to an Array with zero length array

For this we use toArray() method.
import java.util.ArrayList;
import java.util.List;

public class Main {
public static void main(String[] args) {
List carList = new ArrayList();

carList.add("A");
carList.add("B");
carList.add("C");
carList.add("D");

String[] carArray = carList.toArray(new String[0]);

for (String car : carArray) {
System.out.println(car);
}
}
}

o/p:

/*
A
B
C
D
*/
