Answer 1

You were trying to assing an array of arrays to a simple array.
With this modifications the code runs:
for (int i = 0; i < name.length; i++) {
     alist.add(name);
String[] alias = (String[])alist.toArray(new String[0])
Or leave the alist.add() method unchanged and use this line:
String[][] alias = (String[][])alist.toArray(new String[0][0]);
