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

Converting ArrayList to String[] Arrays in Java

Attempting to convert an ArrayList 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. Then, use the toArray(stockArr) method, where stockArr is the newly created array, to populate it with the values from the ArrayList.

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 to a String[] array and access its elements as needed.
