Convert ArrayList<String> to String[] array [duplicate]

Question

I'm working in the android environment and have tried the following code, but it doesn't seem to be working.

String [] stockArr = (String[]) stock_list.toArray(); 

If I define as follows:

String [] stockArr = {"hello", "world"}; 

it works. Is there something that I'm missing?

Answer 1

Try this

String[] arr = list.toArray(new String[list.size()]); 

Answer 2

Use like this.

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);
