学习java中，请教为什么是这样的结果呢？

这么长时间都没有人回答
java版的大师们都这么不屑啊！
下午看看再决定什么......

[superslash]

什么问题啊，没明白

[_-_-_-_-]

你到底是什么问题啊？
说清楚啊

[angle097113]

我想麻烦二位你们仔细看了没有啊，就乱说“什么问题啊，说清楚啊，”
这说的很清楚了，是你们自己看不明白吧，

贴出一堆代码就让人看，哪个会看啊？！

to angle097113(深思不解) :
这样的态度,叫人如何帮你?明明是自己没有把问题说清楚.你就说了"学习java中，请教为什么是这样的结果呢？".你要什么的结果?你希望输出什么结果?你根本没说,别人怎么知道你所说的这样的结果是哪里不符合你的要求?

你至少也要加点描述,说明一下你的问题所在,别人才好忙了解你的问题,才能及时的回答你的问题,你就这样贴出一块代码,别人哪有时间去看啊,要别人去分析每行代码,然后猜测你所要的结果是什么?

问问题也是有学问的,而且,你是在寻人帮助,你这样的态度是不行的,说别人"乱说","没看清楚".希望你能改正你的态度问题.也希望别的朋友也要注意.
