Returns an array containing all of the elements in this list in proper sequence (from first to last element); the runtime type of the returned array is that of the specified array.

Usage

From source file:it.attocchi.utils.ListUtils.java

public static String[] toArray(List<String> aList) {
    String[] res = null;//  ww w  .  jav a 2s. c  o  m

    if (aList != null) {
        res = aList.toArray(new String[aList.size()]);

        // for (String s : anArray) {
        // res.add(s);
        // }
    }

    return res;
