Wednesday (9/26/12)
Warmup:
Agenda:
- Add a (s)ort option to your AddressBook
- In order to compare Strings:
if (str1.compareTo(str2) < 0)
{
System.out.println(str1 + " goes before " + str2);
}
- So inside your AddressBook, you'd have something like this:
if (myContacts[i].getLastName().compareTo(myContacts[j].getLastName()) < 0)
