Double brace initialisation creates an anonymous class derived from the specified class (the outer braces), and provides an initialiser block within that class (the inner braces). e.g.
new ArrayList<Integer>() {{
add(1);
add(2);
}};However, I’m not too fond of that method because what you end up with is a subclass of ArrayList which has an instance initializer, and that class is created just to create one object — that just seems like a little bit overkill to me.
