Plan:
1) arrays, how to use, limitations
2) ArrayLists (both of Object and generics)
3) Inheritance

class Person
{
    static String firstname;
    String lastname;
    String ssn;
    int age;
    static void takeAWalk() { ... }
}

class Customer extends Person
{

}

class Employee extends Person
{
    takeAWalk() { ... }
}


main()
{
    Person x;
    Person.firstName;
    x.firstName;
    x.takeAWalk();
}



4) if there is time, some more Applet material
