Java线程类核心方法1. Thread.currentThread()2. thread.isAlive()3. Thread.sleep(long millis)/Thread.sleep(long millis, int nanos)4. thread.getId()5. Thread.yield()
1. Thread.currentThread()返回当前正在执行的线程对象。示例：2. thread.isAlive()判断当前线程是否处于活动状态。活动状态是指线程已经启动且尚未终止。线程处在正在运行或准备开始运行的状态，就认为线程是存活的。3. Thread.sleep(long millis)/Thread.sleep(long millis, int nanos)...
