<h2 id="缘由">缘由</h2>
<p>今天做项目的时候偶然用到EnumSet，EnumSet平时不太常用，比较陌生，于是点进去看了下源码，发现这个类还是比较有意思的，首先EnumSet是个抽象类，当我们调用EnumSet提供的静态函数创建对象的时候，实际创建的是RegularEnumSet或者JumboEnumSet，前者对应枚举成员少于64个的情况，后者不设枚举成员数量上限，当枚举成员数量大于64时，EnumSet实际创建的对象是JumboEnumSet类型。由于我定义的枚举成员数明显没到64，于是很自然的点进RegularEnumSet继续一探究竟…</p>

<p>这个博客的搭建经历了漫长的探索过程，托管空间从最初的OpenShift到BAE到各类虚拟主机，都或多或少地存在着一些问题。经历过各种折腾，博客目前的状况是：</p>
<blockquote>
<ul>
<li>托管于GitHub，感谢GitHub提供了免费的个人空间</li>
<li>使用博客程序<a href="http://hexo.io/" target="_blank" rel="external">HEXO</a>，一个轻量级的博客框架</li>
<li>使用轻量级“标记语言”<a href="http://en.wikipedia.org/wiki/Markdown" target="_blank" rel="external">Markdown</a>书写博文</li>
</ul>
</blockquote>
<p>本文是博客的第一篇文章，既是试水之作，也是在测试博客的运行状态。博客本身还有许多不完善的地方，将在今后陆续改进。</p>
