1.意思是：原生的，本地的
2.可以修饰：方法
3.它修饰的方法有什么不同
# 语法格式：【修饰符】 class 类{
【其他修饰符】 native 返回值类型 方法名（【形参列表】）；
}
# native修饰的方法看不见方法体，native修饰的方法不是用java语言实现的，而是调用了底层c/c++的代码，这些代码被编译为.dll文件，让java来执行的
4.特殊
-方法该怎么调用还怎么调用
-方法可以被重写
When nothing seems to help, I go look at a stonecutter hammering away at his rock, perhaps a hundred times without as much as a crack showing in it. Yet at the hundred and first blow it will split in two, and I know it was not that blow that did it, but all that had gone before. -- Jacob Riis
