Hello i need to know if there is a way to convert from a generic data structure (say List<T>, Vector<T>, etc) to an array of T, because the method .toArray() returns an Object[]... and i need a T[]...
any words???

try this:
Object[] array = (Object[]) arrayList.toArray(new Object[0]);

i.e for int's
Integer[] a = (Integer[]) arrayList.toArray(new Integer[0]);

you have to use class name instead of data type. works for custom classes too.
