Help With JAVA problem........URGENT

[jason trofimczuk]

Does anyone one have an idea how to tackle the following problem.....any solutions
to this assignment would be helpful:-

Background

A local telephone company is developing coin operated boxes for public use
and will include in each installation a small VDU screen which will be used
to inform users how to operate the telephone. It will respond to coin entry
by informing the user of the time they have purchased for the call. This
time will operate on a count down basis to indicate the time remaining for
the call and will disconnect the call when the time has expired.

Charges

Telephone calls are to be charged as follows:
Local calls 10p for 20 seconds
Trunk calls 10p for 10 seconds
International calls 10p for 4 seconds

Requirement

As an employee of the company you are asked to design and develop a demonstration
Pascal program which could later be used for this purpose. This demonstration
program will operate only from keyboard entry and will only indicate its
actions on the screen.

Specifications

The program, when executed, shall remain in a wait state until RETURN is
pressed. An appropriate message should be displayed whilst the machine is
waiting.

When return is pressed the program will request an entry of the type of call
required indicating; Local, Trunk or International. This is to be entered
as ‘L’,’T’ or ‘I’. This entry must be checked by the program for correctness.

When the user has indicated the type of call required the program should
respond with a request for coin entry (e.g. Insert Coins Now).

There must, at this time be a screen display which indicates the charges
for the type of call requested, such as:
You have requested a local call.
The charge is 10p for 20 seconds.
This will enable users to determine what coins to enter to purchase the time
they are likely to require.

Coins shall be entered by typing in the value of the coins. Only the following
coins shall be valid entries:
5, 10, 20, 50, 100
Each entry shall be indicated on screen with the cumulative total. Coin insertions
shall be terminated by entry of the value zero (0). These entries must be
checked for correctness (validated).

On entry of the zero value, the screen shall clear and a new screen shall
appear which requests the key to be dialled. This number shall be entered
as a string. When the RETURN key is pressed the entry of the number is terminated
and the screen is cleared and the number that has been dialled is displayed
together with the message:

“Now Dialling”

After a short pause the message shall be changed to:

“Connected - Please start your conversation”

Immediately following the ‘Connected..’ message, a display of the time remaining
must appear on the bottom right of the screen. This must be a count down
of the remaining time. (For this program it does not need to be precise but
only approximate in minutes and or seconds).

When the countdown time is zero a final message must appear informing users
that their time has elapsed.

The program must be adequately annotated throughout and a structure chart
test plan MUST be provided. You may write this program as an application,
an applet or using Swing.

Uh, let the person who wrote the specs know that Swing can be used in an
application or applet. And the only real difference between an app and an
applet is how it is run.

To answer your question - First learn Java. If you are not being taught
Java in your class before being given the assignment then dump the class.

And to think that I was just telling one of my buddies how I miss school...
If you have specific questions, great...we're willing to help you out. But
we are not going to do your homework b/c we don't want to pick up your slack
at your first job b/c you can't program worth a sh*t.
