The CurrCon Java Applet displays prices on this web page converted with today’s exchange rates into your local international currency, e.g. Euros, US dollars, Canadian dollars, British Pounds, Indian Rupees… CurrCon requires an up-to-date browser and Java version 1.8, preferably 1.8.0_131. If you can’t see the prices in your local currency, Troubleshoot. Use Firefox for best results.


This essay does not describe an existing computer program, just one that should exist. This essay is about a suggested student project in Java programming. This essay gives a rough overview of how it might work. I have no source, object, specifications, file layouts or anything else useful to implementing this project. Everything I have prepared to help you is right here.

This project outline is not like the artificial, tidy little problems you are spoon-fed in school, when all the facts you need are included, nothing extraneous is mentioned, the answer is fully specified, along with hints to nudge you toward a single expected canonical solution. This project is much more like the real world of messy problems where it is up to you to fully the define the end point, or a series of ever more difficult versions of this project and research the information yourself to solve them.

Everything I have to say to help you with this project is written below. I am not prepared to help you implement it; or give you any additional materials. I have too many other projects of my own.

Though I am a programmer by profession, I don’t do people’s homework for them. That just robs them of an education.

You have my full permission to implement this project in any way you please and to keep all the profits from your endeavour.

Please do not email me about this project without reading the disclaimer above.

This project is mainly an exercise in printing several small logical pages to a single sheet of paper, both sides. This is called 2-up or 4-up printing, depending on how many pages there are per sheet.

Every few years, my address book gets too untidy with changed names and addresses and I start over, copying the most useful names, making errors in the process. I keep the old books around for reference. I would like to automate this process. I’m not rich enough to buy a Palm Pilot, so I ordered a $30.00 USD program from Daytimer to do this.

Supposedly, it will let me maintain the lists electronically and periodically print out subsets of the master address book, so that for example I might just print out a mini address book of my Seattle contacts, or just people I might want to ask for sex, or my Christmas card list, the people I need to contact to organise a high school reunion, just the people I phone frequently…

Your job is to create a portable Java clone of this program.

Things to consider in doing a bang up job to make your code even better than DayTimer’s:
