在Java中将字符串集合转换为字符串数组
首先，创建一个字符串集-
Set<String> setStr = new HashSet<>(Arrays.asList("osCommerce", "PrestaShop", "Magento","Wordpres", "Drupal"));现在，使用toArray()方法转换为字符串数组-
String[] arrStr = setStr.toArray(new String[0]);
示例
以下是在Java中将字符串集转换为字符串数组的程序-
import java.util.Arrays;
import java.util.Set;
import java.util.HashSet;
public class Demo {
public static void main(String[] args) {
Set<String> setStr = new HashSet<>(
Arrays.asList("osCommerce", "PrestaShop", "Magento","Wordpres", "Drupal"));
System.out.println("Set of String: " + setStr);
String[] arrStr = setStr.toArray(new String[0]);
System.out.println("Array of String = "+ Arrays.toString(arrStr));
}
}输出结果
Set of String: [Wordpres, Drupal, PrestaShop, osCommerce, Magento] Array of String = [Wordpres, Drupal, PrestaShop, osCommerce, Magento]
