Java arrays printing out weird numbers and text [duplicate]

Answer 1

Like this:

for (int i = 0; i < arr.length; ++i)
{
    System.out.println(arr[i]);
}

That "weird number" is the reference for the array you printed out. It's the default behavior built into the java.lang.Object toString() method.

You should override it in your own objects if seeing the reference isn't sufficient.
