Convert an ArrayList of String to a String array in Java
At first, let us set an ArrayList of string −
ArrayList<String> arrList = new ArrayList<String>();
arrList.add("Bentley");
arrList.add("Audi");
arrList.add("Jaguar");
arrList.add("Cadillac");Now, use toArray() to convert to a string array −
int size = arrList.size(); String res[] = arrList.toArray(new String[size]);
Example
Following is the program to convert an ArrayList of String to a String array in Java −
import java.util.*;
public class Demo {
public static void main(String[] args) {
ArrayList<String> arrList = new ArrayList<String>();
arrList.add("Bentley");
arrList.add("Audi");
arrList.add("Jaguar");
arrList.add("Cadillac");
arrList.add("Mazda");
arrList.add("Land Rover");
arrList.add("Porsche");
int size = arrList.size();
String res[] = arrList.toArray(new String[size]);
System.out.println("String Array...");
for(String s: res) {
System.out.println(s);
}
}
}Output
String Array... Bentley Audi Jaguar Cadillac Mazda Land Rover Porsche
