Java で ArrayList を String[] 配列に安全に変換する方法

// Define your ArrayList of strings
List<String> stockList = new ArrayList<>();
stockList.add("stock1");
stockList.add("stock2");

// Create a new String array with the same size as the ArrayList
int arraySize = stockList.size();
String[] stockArr = new String[arraySize];

// Copy the ArrayList elements into the String array using toArray()
stockList.toArray(stockArr);

// Print the contents of the String array
for (String s : stockArr) {
    System.out.println(s);
}
