Trying to create an array in Java. What did I just do?

Question

I'm new to Java but not new to programming. I ran the following code in Eclipse:

int[] intArray = new int[5];
System.out.println(intArray);

and received the following output:

[I@17f7be7b

I'm sure StackOverflow already contains the correct way to create an array in Java. What I'd like to know is: what did I do?

Edit: Sorry... The link above my post isn't a duplicate question, and it doesn't answer my question. TylerAndFriends' link is closer, but I was hoping for an explanation of exactly what I printed. Tyler's linked thread says "the default method is to display the object's class name representation, then "@" followed by its hashcode". Can someone elaborate?

Look into array types and the inherited `Object#toString()` method. — Sotirios Delimanolis, Mar 07 '14 at 19:18
Also, ask yourself how and why Java would print the elements of an array. — Sotirios Delimanolis, Mar 07 '14 at 19:21

Use this

       for (int i : intArray) {
            System.out.println(i);
        }
