Separating an array into Strings

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

I have this ArrayList, how do I separate into separate Strings so that I get String a="stock1"; String b="stock2"?

ArrayList<String> list = new ArrayList<String>();
list.add("xxx");
Object[] array = list.toArray();
   for (int i = 0; i < array.length; i++) {
   System.out.println(" value = " + array[i].toString());
   }

just an alternative answer

String[] temp = new String[stock_list.size()];
stock_list.toArray(temp);

now temp[0] contains the first string and temp[1] contains the other.

Seperating an array into Strings

You are mistaken that it's an array. No, it is ArrayList.

ArrayList implements List and it have a method get() which takes index as a arg. Just get those strings back with index.

Returns the element at the specified position in this list.

String a = stock_list.get(0);
String b = stock_list.get(1);

And you should consider to declare your ArrayList like 

List<String> stock_list = new ArrayList<String>();

Which is called as Programming with Interfaces
