Hi all namepros member,

I currently studying, and i need to do a project for my final years. I had this project on hand, but i not sure how to begin with.

I was told to create a A Dynamic Stock Market Data Analysis Tool just like Stock tools

any ideas what programme skills would i need, and how would i do it?
Thanks in advance, really need help.

i recommend using java applets. and on the server side java servlets.
so in short you will need just to study java plus some basic html knowledge you should be able to make it

Ew, try to avoid Java. Flash would be cool though. You could also learn Javascript and make it an AJAX application.

why? java would avoid him facing incompatibility issues. but in the other hand using javascript, ajax, flash and whatever would require him to think about different browsers and incompatibilities between them. besides java is only one language but javascript,ajax and flash are three different things he needs to learn. :hi:

Java is extremely prone to stability and security flaws. It frequently crashes and hinders performance on clients' machines.

And you don't need to learn Flash, Javascript *and* AJAX -- I think you're confused. You could choose to use Flash instead of Javascript, and AJAX is a certain implementation of Javascript. I only presented two different options, not three. And there's no incompatibility issues with Flash and Javascript.

Not quite true, javascript that works in internet explorer will not necessarily work in firefox and vice versa. This is 1 thing that can make ajax problematic.

yes completely true.:blink:

who said java is not stable? java is used every where for programming mobile games, for making web sites appletes and servlets, for desktop applications and many other things.

I knew somebody would say this.

Javascript is totally compatible across browsers when coded properly. Poor design and coding standards will render your Javascript application buggy and unreliable.

I did. And so do millions of other people. Just because it is widely used, unfortunately, does not mean it is a good, solid or lightweight product.

It has nothing to do with adhering to standards and having poor design.

Different browsers interpret standards in different ways. Not only does this affect different browsers but it also affects browser versions etc.

if you consider java is not stable then you can't consider javascript nor ajax nor flash stable.
when you compile java into class file you can have it run over any platform having java virtual machine and you don't need to worry about version or incompatibly issues.
on the contrary there are many flash versions and many browsers that will render your code the way they like.
when programming in javascript you can choose to go in the safe side and keep your self standard but in that case you are going to lose many functionalities and you will not be able to make more than simple functionalities but if you chose the hard way and make advanced programming you are going to face incompatibilities issues and you have to put into consideration every browser out there and make sure your code is fully functional with it or at least to provide another way for different browser to go when it face incompatible code.
in short when you are able to choose between fully functional programming language like java or between scripting programming like javascript or flash. you should choose java to program with.
javascript or flash doesn't worth the trouble you are going to face when you can make the same with easier way using java.
that is my opinion and you are free to do whatever you like of course.

And, yet, Javascript websites work. And they work really well. And they don't require extra installs or system lags. But, I see what you're saying. I often do find some issues when dealing with the DOM and various markup elements, but generally the Javascript code remains the same across.

if you consider java is not stable then you can't consider javascript nor ajax nor flash stable.

How can you make this assertion? If Java IS stable, that doesn't automatically make Javascript and ... AJAX, okay, we need to get you sorted out on this. :p AJAX is an implementation of Javascript. It's a concept; it's a methodology. It is NOT a programming language, platform, or even a script library. We can't consider it seperately from "Javascript," because, in truth, AJAX *is* Javascript.

As I was saying, if Java WAS stable, that does not make Javascript or [AJAX or] Flash automatically stable as well. They are not related.

when you compile java into class file you can have it run over any platform having java virtual machine and you don't need to worry about version or incompatibly issues.

Version issues? Yes, I think so. Only the dozens. Compatibility issues? Perhaps not. But you don't with Flash or Javascript (most generally) either. I'm assuming you don't mean that compatibility and stability are related in this case, however.

on the contrary there are many flash versions and many browsers that will render your code the way they like.

There are many Java versions too.

when programming in javascript you can choose to go in the safe side and keep your self standard but in that case you are going to lose many functionalities and you will not be able to make more than simple functionalities but if you chose the hard way and make advanced programming you are going to face incompatibilities issues and you have to put into consideration every browser out there and make sure your code is fully functional with it or at least to provide another way for different browser to go when it face incompatible code.

I work for a company whose most popular product is actually a Javascript API for one of our certified systems. I recently made a major update to the Javascript framework that we supply (thousands of lines, mind you) -- something that simplifies to just a few lines that the customer puts on their website. We adhere to standards, and our relatively complex product (simplified for many to use easily, something most companies don't offer) is totally compatible. We even rely on a framework and various libraries/plugins, yet it is all entirely compliant in mainstream browsers (Chrome, Safari, Opera, IE6-IE8, and Firefox). Granted, the way we generated or handled the markup/DOM with the Javascript had to be tweaked, but the actual Javascript is compatible. It works. And it's fast, and it works nicely.

in short when you are able to choose between fully functional programming language like java or between scripting programming like javascript or flash. you should choose java to program with.

It depends what you want to do and how you want to deploy it. Again, there's not necessarily a WRONG, just a better/best IMO.

javascript or flash doesn't worth the trouble you are going to face when you can make the same with easier way using java.

Again, depends what you want to do.

that is my opinion and you are free to do whatever you like of course.

Understood. I am just explaining mine as well.

I know ajax is not different language and it is just based on javascript language.
I just wanted to say when you are using javascript you need all of the time to make sure your code is browser compatible and worse when you use ajax you are risking that your site will be nonfunctional or even unacceptable when opened with browsers not supporting your code or a bit older browsers. and countless times I had to check for newest version for flash to be able to open some website or use some feature out there.
if you took a look at big sites you will see all of them very careful about providing an alternative way for users who can't use ajax or new versions of flash.

It depends what you want to do and how you want to deploy it. Again, there's not necessarily a WRONG, just a better/best IMO.

completely agree with you that in some cases it is better to use javascript and ajax and in some other cases it is better to use java.
for example when you need to make your website more dynamic and allow advanced functionalities like submitting data in the same page i believe ajax is the best but in the other hand you should provide a static and old way for incompatible browser users to be able to use your site.
but on the other hand if you need advanced programming functions for example connect to ftp server and upload some things. in that case using java applets is better.
that is in the web side. but looking at other programing platforms java is used wider in mobile applications and desktop applications. you can't use javascript to make a desktop based applications. well you can use flash but again you will face compatibility issues.

This is where we run into issues. You're assuming that Javascript interpreters ("engines") aren't standard or uniform in their function, but that Java is completely universal and traverses various OSes and configurations without issues. Truth is, Java runs on an "interpreter" (technically a type of virtual machine) just as much as Javascript does. Just as there are different engines for Javascript functionality, there are many more different and widespread versions of Java, Java implementations on various platforms, permission elevations, security settings, and other environmental issues. Because Java deals with an entire VM environment, technically problems are more susceptible. Whereas in Javascript, problems with compatibility are generally isolated and convenient.

but on the other hand if you need advanced programming functions for example connect to ftp server and upload some things. in that case using java applets is better.

Or Flash. Or a simple AJAX app with a quick PHP back-end. That requires less overhead on both the client and server's part. Java applets, you will notice, hinder performance on the client's side, at least, most intensively.

that is in the web side. but looking at other programing platforms java is used wider in mobile applications and desktop applications. you can't use javascript to make a desktop based applications. well you can use flash but again you will face compatibility issues.

Okay, generally true, but it looks like we've been discussing the web interface.

Good discussion so far. I'm liking this. I think some excellent points are being made.
