> The code for equals() in the article ensures that the Object passed as an argument is of the same type as itself by trying a typecast; failure results in a ClassCastException which is caught:

> public boolean equals(Object o) {

> if (o == null) {
> return false;
> }

> Worker w;
> try {
> w = (Worker) o;
> }
> catch (ClassCastException e) {
> return false;

> public boolean equals(Object obj)
