java对线程的支持
java.lang
class Threadinterface Runnable run()方法
线程的创建和启动
创建
Thread()
Thread(String name)
Thread(Runnable target)
Thread(Runnable target,String name)
线程常用方法
void start() 启动线程
static void sleep(long millis) 线程休眠
static void sleep(long millis,int nanos)
void join() 使其他线程等待当前线程终止
void join(long millis)
void join(long millis,int nanos)
static void yield() 当前运行线程释放处理器资源
static Thread currentThread() 返回当前运行的线程引用
如何停止线程
