我的任务
分享这个错误是什么意思!
//环境:eclipse+celipseMe
我写了个俄罗斯方块程序（自己动手写的第一个手机游戏，哎！）
运行之后结果是这样的：整个模拟器一闪而过！（是不是有语法错）
下面是控制台的信息！看不懂！可以给我详细讲解一下吗？
如果可能的话，在帮我讲讲如何调式可以吗？（我这没有这方面的资料，书都买不到，不知道他与vc的调式有什么区别，我很喜欢vc的调试）
（刚学没几天，望赐教！）

建议用一下NetBeans 5.0进行Java ME开发。我觉得NetBeans 5.0唯一让我感到新鲜的地方就是它的Java ME开发方式，用起来感觉跟在JBuilder中开发struts似的，用图形化的方式把若干个Form串接起来，每个Form都有一个入口，它的Command命令就是若干个出口，直接把一个Form的出口和另一个Form的入口用一根线连接起来就直接实现了界面切换了，省去了写相似代码的麻烦事儿:)

用JB调试很方便一样也是按F5

谢谢各位：
又奋斗了一个上午，终于有改进了（将书上的代码都去了，这下就真成了我独立开发的第一个小游戏了）
可惜还是有点逻辑错误！
（还是不会调试！）
我想问两个具体的调试问题：
１．设置断点后，如何让程序执行到断点处（vc是按f5)
2.我现在的单步调试按钮全部都变成了灰色，根本没法调试呀！该怎么办？

怎么大家好象对eclipse都不怎么热心呀!eclipse就那么差吗?我可是很看好!
还是没人告诉我这个是什么错误!该如何解决呢?急!!!!
------------------------------------------------------
由于发生内部错误而无法创建此部件。产生该故障的原因是：Unmatched braces in the pattern.

这是数组下标越界了，连出错的方法和出错的行号都已经指出了。
>java.lang.IllegalArgumentException: Unmatched braces in the pattern.
> at java.text.MessageFormat.applyPattern(Unknown Source)
这个说得也非常清楚，调用 java.text.MessageFormat 的 applyPattern 方法时，模板不匹配。楼主将相应的代码贴出来看一下。

debug 去看 eclipseMe安装后的帮助文档设置一下~~
你不会debug以后根本没法出来混

注:里面有小部分代码是书上的!但整个程序的逻辑是我自己想的
----------------------------------------
看来还是有数组越界的问题!
但不会调试,真不知道该怎样去找错误!

又看了一下，好像是 eclipse 本身出了问题。因此，是开发工具的问题。
看来还是 JBuilder 靠得住啊。：）

运行的时候，你已经用catch机制把错误捕捉了，然后又可以继续运行了

谢谢!这是数组下标越界了，连出错的方法和出错的行号都已经指出了
---------------------------------------------------
这个确实是这样的!
但下面的为什么会有这个错误呢?我试了好几个书上的例子,运行没问题!但是一调试就出现下面的类似的错误!
>java.lang.IllegalArgumentException: Unmatched braces in the pattern.
> at java.text.MessageFormat.applyPattern(Unknown Source)
这个说得也非常清楚，调用 java.text.MessageFormat 的 applyPattern 方法时，模板不匹配。楼主将相应的代码贴出来看一下。

这个错误：
java.lang.ArrayIndexOutOfBoundsException
描述是这样的：
Thrown to indicate that an array has been accessed with an illegal index. The index is either negative or greater than or equal to the size of the array.
就是访问的数组索引越界的意思
刚刚看了上面的贴子，可能是使用了不存在的对象（可能是字符串）。
由于对这个库我不熟，所以无法定位具体原因，
你自己也可以定位一下看看，通过异常信息一般都能定位出来问题所在，顺着异常信息看就知道哪个方法调用哪个方法，在哪出的错，再查看一下源码，应该就能搞定。

我请人帮我单步调试了一下主程序，按下f6后，跳出下面的提示信息：
由于发生内部错误而无法创建此部件。产生该故障的原因是：Unmatched braces in the pattern.
单击＂详细信息＂后出现下面的信息：
