a question from whizlab.

"Object o = new int[10];" statement is compiled.

How we can assigned an array of int objects to Object?

and how we can initialized that array then?

thanks all

hello,

arrays are reference types. Any instance of a reference type can be assigned to Object, because every class implicitly extends Object.

To fill this array after the assignment there are no special tricks: It can be cast back to int[].

So briefly, nothing fancy is going on there. It is like any other assignment where the class of the instance (int[]) is a subclass of the declared type (Object).

Anthony,
As Kai writes arrays are of type Objecs.All array of any types (primitives ,non-primitives,even Object arrays)all are of type Object and they make their houses on heaps.
