java 1.5 带来了个 import static。其实就是个“语法糖”，让你得以少写些代码。

原来：
double c2p = Math.cos(2 * Math.PI);

现在：
import static java.lang.Math.*;
double c2p = cos(2*PI);

ps. 记得最开始学 C++ 的时候是比较 bs java 的，认为起又慢又没有啥新鲜的地方。不过最近开始改变了，哪个语言都好，make things done 最重要。语言热门，社区活跃，各类问题的解决方案也比较多、成熟。呵呵。最近在看 DarkStar，发现 java 也不错嘛，至少比 C++ 让人用起来轻松一些，呵呵。
