Compact syntax for instantiating an initializing collection

Question

I\'m looking for a compact syntax for instantiating a collection and adding a few items to it. I currently use this syntax:

Collection collecti

I guess you're thinking about

collection = new ArrayList() { // anonymous subclass
     { // anonymous initializer
         add("1");
         add("2");
         add("3");
     }
}

which, one comapcted, gives

collection = new ArrayList() {{ add("1"); add("2"); add("3"); }}

FUGLY, to say the least. However, there is a variant to the Arrays.asList method : Arrays.asList(T...a) which provides comapcity and readability. As an example, it gives the following line of code :

collection = new ArrayList(Arrays.asList("1", "2", "3")); // yep, this one is the shorter

And notice you don't create an anonymous subclass of ArrayList of dubious use.
