Java – how to create array objects when using parenthesis lists

I understand that when I call its constructor with the new keyword, an array object in Java will be created:

int[] myIntArray = new int[3];

But if I write instead

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

An array object was created, but I didn't call its constructor with new How does this work – how do you create objects in Java without calling constructors?

Solution

In terms of creating array objects, it is a syntax sugar When compiled, it works exactly the same as the standard syntax

The difference is that for the first version, you didn't fill the array - all elements are the default value of int, which is zero

In the second version, you are creating and populating arrays
