Compile error in Java object conversion

Question

I have a problem and I'm wondering if anyone knows why:

if(n.getInfo() instanceof Token){
   //Token abc = n.getInfo();
  System.out.print("ouch!");
}

when it runs, it prints out ouch!.

However, when I uncomment the line

  Token abc = n.getInfo();

it gives a compile error:

error: incompatible types: Object cannot be converted to Token
        Token abc = n.getInfo();

I don't understand, as it is an instance of Token, so how it cannot be converted to Token?

Thanks.

You've tested that it's an instance, you need to add a cast

Token abc = (Token) n.getInfo();
