Hi,
I have found that many times I need to write this simple helper method:
public static @SafeVarargs <T> T[] asArray(T… ts) { return ts; }
I usually need this when I have several implementations I’m comparing and I
want to change the code for observing one of them to observing two or more of
them in sequence. I feel that in this case switching from operating on one
object to operating on an unknown List implementation (from Arrays.asList) is a
too drastic change when all I need is put a for-loop around some code and
iterate.
The code for which I have to write this method is often some variation of
something like this:
Comparator<Object> sort1 = (x, y) -> (Integer) x - (Integer) y;
Comparator<Object> sort0 = (x, y) -> (int) (Math.pow((Integer) x, 2.0) -
Math.pow((Integer) y, 2.0));
// Have to use a helper method here
Comparator<Object>[] sorts = asArray(sort0, sort1, sort2, sort3);
Please consider and add this simple method to Arrays.

Have a nice day,
