Why does Java give this output?

When trying to run the following code:

public static void main(String[] args) {
    int num_amount = 7;
    int[] num_array = {3, 4, 1, 1, 2, 12, 1};
    System.out.println(num_array.length);
    for (int i = 0; i < num_array.length; i++) {
        num_array[i] = 0;
        System.out.println(num_array);
    }
}

This is the output i get:

7
[I@ea30797
[I@ea30797
[I@ea30797
[I@ea30797
[I@ea30797
[I@ea30797
[I@ea30797

Has anyone ever experienced this "unusual" result? If so, what solution did you try out? Thanks in advance.

>Solution :

If you want to print the contents of an array you can use Arrays.toString.

System.out.println(Arrays.toString(num_array));
