客户端Java与（Adobe）Flash为Web应用程序，什么选择和何时 [英] Client Java vs (Adobe) Flash for web applications, what to choose and when

问题描述

几年前，客户端Java不适合Web开发，因为很大一部分Web用户没有安装Java。 （我不记得确切的数字，超过10％）。

现在我看到一个大网站的Google Analytics（分析）统计数据，它告诉大约98％的用户安装了Java。

这些统计数据是非常偏向Javascript的使用？据我了解，Google Analytics（分析）只会测量使用Javascript的用户。

其他大型网站的图片是否相似？ > 客户端Java与Flash相比有没有阻止缺点？编辑：我的意思是java applets主要是java WebStart似乎不是适用于普通用户。

我提到Javascript只是为了描述Google Analytics的工作方式。 我写了我的文凭项目，我不得不在Flash和Java小程序之间进行选择。这里有一些优点和缺点：$ b​​
$ b Java小程序：

[plus]你用Java编程，这是成熟和稳定的

[plus]你可以使用Java GUI框架打包大量的打孔

[减号]用户首次用applet点击页面时，必须初始化JVM，即使在快速的计算机上，这也可能需要几分钟的时间

[减号] Applets并不意味着被用作动画媒体;当然，你可以做的东西，但它就像在C编程 - 你从头做一切事情

例如：我需要显示数据包在两台路由器之间移动。数据包必须是某种类型的控件，如按钮或水平。这个动画可以在Flash中的一行代码中定义，其中所有的对象都来自一些可以动画的基础对象。我无法在Java中找到合适的解决方案。

Flash：

• [plus]真的非常专注于动画;


• [加] ActionScript实际上是一种面向对象语言


• ActionScript减肥，只有少数支持者。如果您遇到困难，请准备搜索隐晦的日语论坛以获取解决方案。
ActionBript可能是面向对象的，但它缺少很多功能，例如枚举，完全成熟的接口，线程!!!!）等。

• [闪存]被设计为供非技术人员使用 - 他们只是使用创作工具;我写了一切代码，它工作，但它是一个痛苦。

我的结论：

我非常期待动画的编程范式，丰富的客户端界面ps：Silverlight似乎到目前为止是一个失望，也许微软将注入一些$。$ / b>

A few years ago client Java was unsuitable for web development because a remarkable part of web users did not have Java installed. ( I don't remember exact numbers, more than 10%).

Now I see the Google Analytics stats for a big site and it tells that >98% of users have Java installed.

Is these stats very biased by Javascript usage? As I understand Google Analytics measure only users that has Javascript.

Is the picture similar on other big sites?

Does client Java have really "stopper" drawbacks compared to Flash?

EDIT: I mean java applets mainly, java WebStart seems to be not suitable for average user.
I mention Javascript only to describe the way Google Analytics works.

解决方案

When I wrote my diploma project, I had to choose between Flash and Java Applets. Here are some pros and cons:

Java Applets:

• [plus] you program in Java, which is mature and stable
• [plus] you can use the Java GUI frameworks that pack a lot of punch
• [minus] the first time the user hits the page with the applet, the JVM must be initialized and this can take up to a few minutes even on a fast computer
• [minus] Applets are not meant to be used as animation media; sure, you can do stuff, but it is like programming in C - you do everything from scratch

example: i needed to show a data packet as it moved between two routers. The packet must be a control of some sort, like a button or smth. This animation can be defined in 1 line of code in Flash, where all objects derive from some base object that can be animated. I could not find a suitable solution in Java.

Flash:

• [plus] really really focused on animations;
• [plus] ActionScript is actually an OO language
• [minus] ActionScript is sloppy, bughish and has only a few supporters. If you are stuck, be prepared to search obscure Japanese forums for solutions
• [minus] ActionSCript may be OO, but it lacks a lot of features, like Enums, fully fledged interfaces, threads (!!!!) etc.
• [minus] Flash was designed to be used by non-tech people - they just use the authoring tool; I wrote code for everything and it worked, but it was a pain.

My conclusion:

I eagerly await a programming paradigm for animations and rich client interfaces.

ps: Silverlight seems to be a disappointment so far, maybe Microsoft will inject some $ into it.
