java - Initializing array with values - should I explicitly instance the class or not?

Question

I often see arrays being initialized like this:

String[] array = new String[] { "foo", "bar", "baz" };

But reading the Language Basics - Arrays shows that the short syntax doesn't require explicitly instancing the constructor:

Alternatively, you can use the shortcut syntax to create and initialize an array:

 int[] anArray = { 
     100, 200, 300,
     400, 500, 600, 
     700, 800, 900, 1000
 };

So, assuming these two methods of initialization:

String[] array = new String[] { "foo", "bar", "baz" };
String[] array2 = { "foo", "bar", "baz" };

Is there any difference between these? Both seems to work the same, in that case should I assume that the second one implicitly calls the new String[] and the first one is just a more verbose way, or is there more to it behind the scenes?

Starting with Java so sorry if this is way too stupid of a question, but I couldn't find anything about this in the web.

Answer 1

The two methods are equivalent. Note, however, that the concise syntax can only be used in variable declarations. Outside variable declarations you have to use the verbose syntax:

    String[] array;
    array = new String[] { "foo", "bar", "baz" }; // OK

    String[] array2;
    array2 = { "foo", "bar", "baz" };             // ERROR
