Wouldn't this be more likely? class Person {
public void listenToPhone(Telephone t) {
t.addTelephoneListener(
new TelephoneAdapter() {
public void telephoneRang(TelephoneEvent e) {
System.out.println("I'll get it!");
((Telephone)e.getSource()).answerPhone();
}
}
);
}
} class AnsweringMachine implements TelephoneListener {
private int count = 0;
public void telephoneRang(TelephoneEvent e) {
System.out.println("AM hears the phone ringing.");
if(count > 4) {
((Telephone)e.getSource()).answerPhone();
}
count++;
}
public void telephoneAnswered(TelephoneEvent e) {
System.out.println("AM sees that the phone was answered.");
count = 0;
}
} Your example has the phone answering itself.
