Sorry to send the question again. I forgot putting the example code in the
previous email. The code is as follows. It works fine. However, my code does
not.
public class AddressBookService {
private HashMap entries = new HashMap();
private MyAddress myaddr = new MyAddress();
/**
* Add an Entry to the Address Book
* @param entry
*/
public void addEntry(Entry entry) {
this.entries.put(entry.getName(), entry);
}
/**
* Search an address of a person
*
* @param name the name of the person whose address needs to be found
* @return return the address entry of the person.
*/
public Entry findEntry(String name) {
return myaddr.getAddr(name);
}
}
