How to see if an object is an array without using reflection?
arrays, gwt, instanceof, java
Solution
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.
Problem
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 not allowed to use reflection :( I would love to implement the following methods without using refelection: ``` private boolean isArray(final Object obj) { //??.. } private String toString(final Object arrayObject) { //??.. } ``` BTW: neither do I want to use JavaScript such that I can use it in non-GWT environments.
