Java new Object[]{...} syntax

Question

I don't recognize this kind of form Java syntax for constructor - granted I do very little Java now (taken from there):

new PersistentArrayMap(new Object[]{formKey, form});

I was expecting something along the lines of new Object(...) as parameter. Could someone decompose the above line ?

Answer 1

You are creating new Object array Object[] initialised to {obj1, obj2}

Answer 2

It is a way of declaring and initializing an array in java. A simpler example is the following:

int[] myIntArray = new int[]{1,2,3};
