## 3.4 yield ##
public static native void yield();这是一个静态方法，一旦执行，它会是当前线程让出CPU，但是，需要注意的是，让出的CPU并不是代表当前线程不再运行了，如果在下一次竞争中，又获得了CPU时间片当前线程依然会继续运行。另外，让出的时间片只会分配**给当前线程相同优先级**的线程。什么是线程优先级了？下面就来具体聊一聊。

现代操作系统基本采用时分的形式调度运行的线程，操作系统会分出一个个时间片，线程会分配到若干时间片，当前时间片用完后就会发生线程调度，并等待这下次分配。线程分配到的时间多少也就决定了线程使用处理器资源的多少，而线程优先级就是决定线程需要或多或少分配一些处理器资源的线程属性。
