Can I override the equals() method to take a parameter other than Object?

If you are trying to override a method with a different argument list, that isn't overriding, but overloading. In order for the method to be properly overridden, and thus called appropriately, the subclass method signature must explicitly match that of the superclass. In the case of equals() that means the return type must be boolean and the argument must be Object.
