# 將`HashSet`轉換為數組 > 原文： [https://beginnersbook.com/2014/08/converting-a-hashset-to-an-array/](https://beginnersbook.com/2014/08/converting-a-hashset-to-an-array/) 這是將`HashSet`轉換為數組的程序。 #### 程序 ```java import java.util.HashSet; class ConvertHashSettoArray{ public static void main(String[] args) { // Create a HashSet HashSet<String> hset = new HashSet<String>(); //add elements to HashSet hset.add("Element1"); hset.add("Element2"); hset.add("Element3"); hset.add("Element4"); // Displaying HashSet elements System.out.println("HashSet contains: "+ hset); // Creating an Array String[] array = new String[hset.size()]; hset.toArray(array); // Displaying Array elements System.out.println("Array elements: "); for(String temp : array){ System.out.println(temp); } } } ``` **輸出：** ```java HashSet contains: [Element1, Element2, Element3, Element4] Array elements: Element1 Element2 Element3 Element4 ```
