对不住我非常不看好谷歌。
之前我说了我对苹果和乔布斯非常佩服，虽然这种佩服不是完全立场上的支持。苹
果和乔布斯最大的一点就是认准了会做到最大限度和极限。不管他们过去成功还是失败的产品。现在大家都在说乔布斯去世之后苹果会如何如何，什么创新和用户体验的坚持如何如何，都对。但是更大的一条，一个企业如果有一个老乔那样执着甚至顽固的坚持的头头，他们就多了一份别人没有的“信念”。后乔布斯时代的苹果，在这一点上就不一定了。
谷歌呢？别的不说，就举个几个例子看看这几年的大事：开通免费WIFI，竞购无线频道，还有就是安卓以及收购MOTO的手机部门了。前两件事情我实在不明白他们最终做到什么程度了，WIFI在MOUNTAIN VIEW还有一些机场推出了这个免费WIFI系统。SO?多少人在用，目的是什么？带来了什么技术革命和更重要的，基本面上对GOOGLE的好处？几乎没有太多。算我目光短浅。我估计GOOGLE... 阅读全帖 |

Hehe, but from what I heard and my experience, it's not. If you are real in

must know the most important part of embedded industry is real time

that.

发帖数: 137 | 23 It's usually J2ME (MIDP/CLDC), very few use stuff like KJava. But now it's
becoming unified. Most handset OS would also give you information about the
Java system information directly.
BTW: If you want to do a System.out.println("hello world"), it won't display
on the phone, because the standard output for most java phones are the data
connector (to be connected to the computer). Also, you need to put your app in
specific package before the phone would take it, which depends on the actual

强烈同意，SUN自己的东西简直没法用。不过他的运气也是比较好，有IBM，Oracle,
BEA这些公司对JAVA鼎力支持，不然JAVA恐怕早死翘了。
现在看来Java在J2EE和J2ME两块好像都站住脚了，我们这些靠Java吃饭的应该可以睡觉
踏实一点了吧。还记得几年前JDJ上有篇评论，说JAVA活不了两年了，呵呵。

I'd go with ArrayList unless your project is on J2ME.
Just remember to use Boolean.valueOf(value) rather than new Boolean(value)
everytime when you insert an element. That way you won't end up with
a bunch of different Boolean objects. |

发帖数: 562 | 44 It depends on whether your J9 is CDC or CLDC. It seems that you are using
CLDC/MIDP J9.
CLDC classes have one extra preverification step. Classes compiled under
Java SE will not be able to run.
Palm has discontinued the J9 JVM (CLDC/MIDP) for a while.
",j9仅支持awt,swt,有swing的话不能运行。"
CDC has AWT.
CLDC does not have any of those UI packages. It only supports LCDUI, which
is very limited UI designed for cell phones. |

发帖数: 4260 | 45 Then mine is probably CLDC, although I totally have no idea what CLDC and
CDC mean. Is there a CDC JVM for Palm?
No, I haven't tried VNC client. I prefer RDP because I don't have to install
a server on it. |

发帖数: 684 | 46 J9 comes with 2 flavors, CLDC/MIDP or CDC/PP, one for low end wireless

CDC/PP和J2SE1.4接近，jar也是一样的，一般两个平台上都能运行的。 |
