How to Properly Convert an ArrayList to a String[] Array in Java?

Converting ArrayList<String> to String[] Arrays in Java

Attempting to convert an ArrayList<String> to a String[] array using the toArray() method may not always work as expected. The original question highlights this issue.

To successfully perform this conversion, the correct approach is to create a new String[] array of the same size as the ArrayList<String>. Then, use the toArray(stockArr) method, where stockArr is the newly created array, to populate it with the values from the ArrayList<String>.

Code Example:

List<String> stockList = new ArrayList<String>();
stockList.add("stock1");
stockList.add("stock2");

String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);

for(String s : stockArr)
    System.out.println(s);

Output:

stock1
stock2

By following this approach, you can successfully convert an ArrayList<String> to a String[] array and access its elements as needed.
