<br />
重构�E�序的目的，不是因�ؓ(f��)�E�序不能用才要你去重构，重构的目的是因�ؓ(f��)一、你的代码，被�h看的�ơ数�Q�远比它用到的次数多�Q�二、重构有利于你发现问题，让你的程序结构优化，因此可复用性更强，遵守�?ji��n)知识的唯一性，DRY 原则�Q�三、如果你要改动这�D�代码，那么先重构，使得你的代码好改�Q�这实际是在��Z��的未来减���工作量�Q�而且一�D�优�U�的代码，带给你的价��|���q�比你每�ơ都要Ctrl+C�Q�Ctrl+V 大得多�?br />
<br />
写代码，要让你的代码�W�一�ơ呈现在别�h面前的时候，像读��p��一般，那么你的代码功底是��够了(ji��n)。你的代码就可以�U�C��你最好的文����?ji��n)，其余什么文���，大可不必�Q?br />
<br />
��Z��昨天的经验，我新�ȝ���?ji��n)两条�?x��)<br />
一、经�怋�用重构方法extract method 的�h�Q�会(x��)发现�Q���L��可以省掉一些��(f��)时变量。这是好事，但这可能�?x��)造成如下的结果：(x��)<br />
<br />
<span style="background-color: #b8c2af;">method_one(method_two(method_three(method_four())))</span><br />
<br />
也就是说�Q�很可能�?x��)导致这�U�长串的嵌套�Q�导致程序可��L��的下降�Q���人看的晕头�{向。那么如何解军_���Q�其实是一个度的问题。我�l�自己定�?ji��n)一个规矩，临界�Ҏ(gu��)��三个函数�q�样�U�联��h���Q�如果超�q�三个，我就���它们拆开。比如说上面�q�个���例子，我会(x��)拆成�Q?br />
<br />
<span style="background-color: #b8c2af;">
arg = method_three(method(four));</span><br />
<span style="background-color: #b8c2af;">method_one(method_two(arg));</span><br />
<br />
虽然���费�?ji��n)一个��(f��)时变量，但是�q�样���可以让��Z��眼看懂我的意思，可读性提升，修改��h��自然也会(x��)�Ҏ(gu��)��些�?br />
<br />
二、写�q�Java I/O 的�h�Q�肯定看到过�q�样的程序：(x��)<br />
<br />
<span style="background-color: #b8c2af;">
Reader in = null;<br />
Writer out = null;<br />
try<br />
{<br />
&nbsp;&nbsp;&nbsp; in = new InputStreamReader(socket.getInputStream(),"utf8");<br />
&nbsp;&nbsp;&nbsp; out = new OutputStreamWriter(socket.getOutputStream(),"utf8");<br />
<br />
/**<br />
&nbsp;* some TODOs here<br />
&nbsp;*<br />
**/<br />
}catch(IOException ioe)<br />
{<br />
&nbsp;&nbsp;&nbsp; System.err.println("error message");<br />
&nbsp;&nbsp;&nbsp; ioe.printStackTrace();<br />
}<br />
finally<br />
{<br />
&nbsp;&nbsp; try<br />
&nbsp;&nbsp;&nbsp; {<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; if(in != null)<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;  &nbsp;&nbsp;&nbsp; in.close();<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; if(out != null)<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;  &nbsp;&nbsp;&nbsp; out.close();<br />
&nbsp;&nbsp;&nbsp; }catch(IOException ioe2)<br />
&nbsp;&nbsp;&nbsp; {<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;  System.err.println("some error message");<br />
&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;  ioe2.printStackTrace();<br />
&nbsp;&nbsp;&nbsp; }<br />
}</span><br />
<br />
怎么说呢�Q�这�D�代码看上去�Q�其实是够好�?ji��n)，其实不重构也是可以的。也许我偏执吧，我认为它不够好，因�ؓ(f��)�Q�首先，大段的try catch 的确�?x��)捕获异常，但是�q�段代码臛_��有好几段是会(x��)独立抛出异常的，�q�里包含�?ji��n)四个IO 实例的创建和销毁，�q�四�D�代码如果出错都�?x��)抛出异常，那么你捕��L(f��ng)��到底是哪个呢�Q�其�ơ，没有把功能段合理分开�Q�这�D�代码的逻辑功能实际上是两个�Q�一个是读，一个是写，那么合�ƈ在一��P��首先��序很�ؕ�Q�其�ơ容易让阅读的�h产生困惑�Q�从而造成代码可读性差。我是这样做的：(x��)<br />
