Initialization of an ArrayList in one line

Question

I wanted to create a list of options for testing purposes. At first, I did this:

ArrayList places = new ArrayList();
places.add(\         


        

Answer 1

Why not make a simple utility function that does this?

static  ArrayList ll(A... a) {
  ArrayList l = new ArrayList(a.length);
  for (A x : a) l.add(x);
  return l;
}

"ll" stands for "literal list".

ArrayList places = ll("Buenos Aires", "Córdoba", "La Plata");
