線程的創(chuàng)建：Thread()? Thread(String name)?? Thread(Runnable target)?? Thread(Runnable target,String name)

static void sleep(long millis)

static void sleep(long millis,int nanos) //線程休眠

void join()

void join(long millis)

void join(long millis,int nanos) //使其他線程等待當(dāng)前線程終止

static void yield()//當(dāng)前運(yùn)行線程釋放處理器資源

static Thread currentThread() //返回當(dāng)前運(yùn)行線程引用
