©1996-2012 Roedy Green, Canadian Mind ProductsThis 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.
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, 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.
I would like it if I could insert a bit of canned Javascript/Java bubblegum in every web page containing java that did the following:You are using Opera version 5.0. You need to upgrade your browser to use this Applet.
 |
Opera 8.53 with the Java 1.7.0_04 Plug-in. This is the browser I use myself, so it is the one most likely to render correctly. |
 |
Sun’s Java 1.5.0_05 Plug-in add on |
| Click to download the latest browser software |

You are using Opera version 8.5 with and older Java Plugin 1.4.2. You need to upgrade your plug-in, but the browser is fine as is.

Sun’s Java 1.5.0_05 Plug-in add on |
| Click to download the latest browser software |

| This Applet requires one of the following up-to-date browsers: | |||
| Click the corresponding browser icon to download the latest free browser software, or click the browser name for more information. | |||
|---|---|---|---|
 | Firefox | 12.0 | with the Java 1.7.0_04 JRE (Java Runtime Environment). Its support of Java is erratic. Most widely supported next to IE. Many add-ins. Very fast rendering. Weak on table rendering. Best for printing. |
 | SeaMonkey | 2.9.1 | with the Java 1.7.0_04 JRE. Similar to Firefox, with integrated Email. |
| Opera | 11.64 | with the Java 1.7.0_04 JRE. Cannot handle JavaScript Google AdSense ads. Buggy JavaScript generally. Otherwise fast and light. Accurate CSS. Often hangs when you exit. |
 | Google Chrome | 19.0.1084.52 | with the Java 1.7.0_04 JRE. Frequently updated. Has no edit source button. Fast starting. Flaky supports of Applets and Java Web Start. Poor downloading. Handles foreign language sites particularly well. |
 | Safari | 5.1.5 | with the Java 1.7.0_04 JRE. For both Macs and PCs. Some rendering problems. Simple and stripped down. |
 | IE9 | 9.0.8112,16421 | with the Java 1.7.0_04 JRE. Not recommended. This browser is hopeless at Java, especially the 64-bit version. Some websites will work with no other browser. |
 | IE8 | 8.0.7601.17514 | with the Java 1.7.0_04 JRE. Out of spite, blocks Java unless you OK. It has many bugs and crashes frequently. Renders column classes correctly. |
 | IE7 | 7.0.6000 | with the Java 1.7.0_04 JRE. It is pain to get Java Web Start working. |
 | IE6 | 6.0.2800 | with the Java 1.7.0_04 JRE. Not secure. |
 | Avant | 2012:171 | with the Java 1.7.0_04 JRE. It is a fast browser, especially at starting up. Has problems with JavaScript. Excellent at rendering and printing tables. It uses the Firefox rendering engine. Handles Applets, but has trouble with Java Web Start. |
| Oracle’s Java | 1.7.0_04 | JRE |
It would be nice to just provide a list of suitable browser names and a range of suitable version numbers including + to mean "any future version" and be done with it.
This is mainly a project using search engines to scrounge up snippets of code to recognise various browsers, then organising it into a coherent whole. It is likely more JavaScript that Java, but the users of the end product will be grateful Java programmers.
