Java ME值得学习吗？
我看到很多人写 Java ME (J2ME) 正在消亡。这是真的吗？它的未来是什么？如果我想为智能手机创建应用程序，我应该学习 Java ME 吗？如果是，从哪里开始？
I have seen many people writing that Java ME (J2ME) is dying. Is it true? What is its future? Should I learn Java ME if I want to create apps for smartphones? If yes, where to start?

我已经开发 J2ME/Java-Me 多年了，现在根据我的应用程序的下载统计数据，我发现大部分下载 (90%) 来自发展中国家。因此，如果您的目标用户不是来自西方国家，请继续学习 J2ME，否则学习 Android 和/或 iPhone。
I've been developing for J2ME/Java-Me for several years and now I see based on download statistics of my applications, most of downloads (90%) comes from developing countries. So if your target users are not from Western countries - go ahead learn J2ME, otherwise learn Android and/or iPhone.
如果我是你，我就会开始学习为 Android 和 iPhone 编写应用程序。
Java ME 可能还没有完全消亡，但使用这些你会做得更好。你们产品的潜在市场会更大，而且会越来越大，我敢打赌，这也会更有趣。
If I were you, I'd start learning to write apps for Android and iPhone.
Java ME may not be entirely dead, but you'll do much better with these. The potential market for your products is much bigger and keeps getting even bigger, and I bet it would be a lot more fun, too.
我曾经为 j2me 开发。我认为这一切都取决于需求。现在，我收到的需求主要是 iPhone 应用程序。 Android 也在取得进展，但我想说，每 10 个 iphone/ipad 应用程序，我会得到大约 2-3 个 Android 应用程序，也许还有 1 个 j2me 应用程序。哦，那是在英国。这一切都取决于你。如果你想成为自由职业者，我建议你去学习 Objective c 。这是一种非常简单的语言，在我看来比 JAVA 更简单。
I used to develop for j2me . I think it all depends on demand. Right now, i mostly get demands for iphone apps. Android is also making its way but i'd say for every 10 iphone/ipad apps, I get about 2-3 android apps and maybe 1 j2me app. Oh and that's in the uK. It all depends on you. If you want to freelance, I'd say go and learn objective c . It is a very simple language and simpler than JAVA imo.
现在很多手机都支持J2ME。所以它非常有用。J2ME不需要高成本配置，所以很多手机都支持它。不仅手机很多小型设备都支持J2ME。所以J2ME正在消亡是错误的一句话。J2ME正在成长。
如果你只考虑移动领域，那么你会认为 J2ME 正在消亡，但如果你从现实世界的角度思考，那么你就会理解 J2ME 的需求。今天，许多设备，如机顶盒、家用电器、无线电话、等使用/支持 J2ME。
J2ME也有很多工作机会。
目前智能手机市场Android、Blackberry、IPhone的发展规模大于J2ME。
但是J2ME中的一些点、库、概念等在Blackberry、Android等中使用。
J2ME 非常古老，它将为现代智能手机技术（如 Android、Blackberry 等）奠定基础。
谢谢&问候，

Nowadays many phones support J2ME.So it is very usefull.J2ME does not need hight cost configurations so many phones support it.Not only phones lot of small devices support J2ME.So J2ME is dying is wrong sentence.J2ME is growing.
If u think only in mobile circles then u get a view that J2ME is dying but if u think in the view of real world then u understand the need of J2ME.Today many devices such as set-top boxes,home applainces,wirless phones,etc uses/support J2ME.
J2ME also had many job oppurtunities.
At present in smart phone market the Android,Blackberry,IPhone are grows larger than J2ME.
But some of the points,libraries,concepts,etc in J2ME are used in Blackberry,Android,etc.
J2ME is very old and it will enable the ground for the modern Smart Phone technology such as Android,Blackberry,etc.
Thanks & Regards,

取决于您想要的目标手机，正如您提到的智能手机而不是功能手机，我建议使用 Android，特别是如果您已经有 Java 背景，否则选择 iOS（iPhone、iPod Touch 和 iPad）或 Android，如这些对于开发人员来说更加有趣，并且有更好的文档和示例开源应用程序可供他们使用，并且能够相对轻松地在设备上部署和调试
Depends on which phones you want to target, as you have mentioned smartphones rather than feature phones, I would suggest Android, especially if you are already coming from a Java background, otherwise either iOS (iPhone, iPod Touch and iPad) or Android, as these are far more enjoyable for a developer and have far far better documentation and example open source applications available for them as well as being able to deploy and debug on device relatively painlessly
不要忘记，Android 和 iPhone 应用程序的预期 UI 修饰远远高于 MIDlet。这需要花费大量的时间和精力来创建。
Don't forget that the expected UI polish of Android and iPhone apps is far higher than MIDlets. This takes a lot of time and effort to create.
