array question

[Douglas Chorpita]

In Java, an Monkey array can be assigned to an animal array.

The following code is legal:

 
class Animal {}
 
class Monkey extends Animal {}
 
class Main {
 
   void method() {
      Animal[] array = new Monkey[ 20 ]; 
   }
}
 

Java doesn't allow this, however. Why? Is "Object" a special case?

 
class Animal {}
 
class Monkey extends Animal {}
 
class Main {
 
   void method() {
      Object[] array = new Monkey[ 20 ]; 
   }
}

Both code snippets are completely legal and will compile and run without errors. I don't know how you reached your observation.

The only arrays where implicit casting is not permitted are arrays referencing primitives types.

Confirmed.

Sorry. My fault.

I was doing a bunch of tests, all in one file.

I had created a class called "Object" in my own package. I know this is stupid, but I wanted to see (with my own eyes) that a class called "Object" would compile and extend "java.lang.Object".

This is why I got the error.

Thanks for the help!!!
