multi-threading)  and identify  the classes/package through which they

This is a Project Assignment.  Answer the following question using
Java.

Suppose that you have to computerize a car show room which keeps the
latest models of cars, and provides post sales services to customers.

(i)	List all important classes, their data structures and other
attributes.
(ii)	Draw an inheritance diagram for the  entire application which
should comprise  of base classes and sub-classes.

Don't be ridiculous. Go and do your own homework.

Hint:
See:

,especially this part:

2. your Java textbook

Those should provide the answers, supposing you are not too lazy to do
some reading.

All of us.

I could go on about what Hitler said, but I think all classes are
equal.

At my college, the top class was our Senior Seminar.

Forget it.

You obviously have no clue whatsoever about :
- *why* you get homework,
- *why* you need to do it _yourself_, and
- the purpose of education in general.

Don't spend any time on your education until you know the answers to all
three points above: it's wasted energy (you've just proven that).

Declares that the class contains an abreviated, yet concise summary of
it's features before any more elaborate methods. This is useful to
to quickly decide if a given class can be useful for you

> §	Final Class

Declares that this class can not ever contain references to other objects.
The garbage collector needs to know which classes are "final" in order to
be able to decide what can be deleted to create new objects.

Think of "final classes" as the leafs in the Object Tree.

> §	Public

Declares that the modified object is considered "public property". This
means that all threads (see there) do all the work in methods of this
class communally. Usually considered a bad idea, but left in the language
specification by insistance of the USSR

> Question 2:	Through a small example, Explain the following:
>
> i)	Concept of Subclasses, Super classes and  Inheritance

A Subclass is a class contained by another class. Subclasses were added
to the language to allow more complicated code.

Super Classes are classes that have proven their usefulness and utility
time and again. Once a year, in a popular vote, this year's five super
classes are elected. Super Classes may display "This is a Super Class"
on the screen whenever their methods are called

Inheritance is the concept of destroying an object to access the data
it contains. Just like in real life, you inherit valuable things
once someone close to you dies. Since you can not access data of
"life" objects, they need to die before you can extract their information

The Top class is without a doubt
javax.security.auth.login.AccountNotFoundException. Why? because it
became a super class three times in a row, and the comitee decided to
commemorate that event by declaring it the top class.

Trick Question. There are no features. There are only bugs.

Hmm, car show room. Kind of a classic example. Many plebians will try to
convince you that you need classes like 'Car'. But they forget the basic
classes like CuteSalesGirl or  DumbCustomerWithHeapsOfUnusedCashToSpare
.

Begin by building a GUI that supports the latest in 3d technology to
display the cars on display (and the CuteSalesGirl).
