How can I see in Java if an Object is an array without using reflection? And how can I iterate through all items without using reflection?

I use Google GWT so I am n

Answer 1

You can use Class.isArray()

public static boolean isArray(Object obj)
{
    return obj!=null && obj.getClass().isArray();
}

This works for both object and primitive type arrays.

For toString take a look at Arrays.toString. You'll have to check the array type and call the appropriate toString method.
