在 Java 中将字符串集合转换为字符串数组

首先，创建一个字符串集合 −
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 中将字符串集合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("字符串集合:" + setStr);
String[] arrStr = setStr.toArray(new String[0]);
System.out.println("字符串数组 = "+ Arrays.toString(arrStr));
}
}
输出
字符串集合:[Wordpres、Drupal、PrestaShop、osCommerce、Magento] 字符串数组 = [Wordpres、Drupal、PrestaShop、osCommerce、Magento]
