前面的文章已经介绍了有关线程的调度，接下来介绍如何使用方法对线程进行控制

1、线程休眠

public static void sleep(long millis)

/* * 线程休眠 *        public static void sleep(long millis) */public class ThreadSleepDemo {    public static void main(String[] args) {        ThreadSleep ts1 = new ThreadSleep();        ThreadSleep ts2 = new ThreadSleep();        ThreadSleep ts3 = new ThreadSleep();         ts1.setName("zhangsan");        ts2.setName("lisi");        ts3.setName("wangwu");         ts1.start();        ts2.start();        ts3.start();    }} public class ThreadSleep extends Thread {    @Override    public void run() {        for (int x = 0; x < 100; x++) {            System.out.println(getName() + ":" + x + ",日期：" + new Date());            // 睡眠            try {                Thread.sleep(1000);            } catch (InterruptedException e) {                e.printStackTrace();            }        }    }}

2、线程加入

public final void join()

public class ThreadJoin extends Thread {    @Override    public void run() {        for (int x = 0; x < 100; x++) {            System.out.println(getName() + ":" + x);        }    }}/* * public final void join():等待该线程终止。  */public class ThreadJoinDemo {    public static void main(String[] args) {        ThreadJoin tj1 = new ThreadJoin();        ThreadJoin tj2 = new ThreadJoin();        ThreadJoin tj3 = new ThreadJoin();         tj1.setName("zhangsan");        tj2.setName("lisi");        tj3.setName("wangwu");         tj1.start();        try {            tj1.join();        } catch (InterruptedException e) {            e.printStackTrace();        }                tj2.start();        tj3.start();    }}

3、线程礼让

public static void yield()

public class ThreadYield extends Thread {    @Override    public void run() {        for (int x = 0; x < 100; x++) {            System.out.println(getName() + ":" + x);            Thread.yield();        }    }}/* * public static void yield():暂停当前正在执行的线程对象，并执行其他线程。  * 让多个线程的执行更和谐，但是不能靠它保证一个线程一次。 */public class ThreadYieldDemo {    public static void main(String[] args) {        ThreadYield ty1 = new ThreadYield();        ThreadYield ty2 = new ThreadYield();         ty1.setName("zhangsan");        ty2.setName("lisi");         ty1.start();        ty2.start();    }}

4、后台线程

public final void setDaemon(boolean on)

public class ThreadDaemon extends Thread {    @Override    public void run() {        for (int x = 0; x < 100; x++) {            System.out.println(getName() + ":" + x);        }    }} /* * public final void setDaemon(boolean on):将该线程标记为守护线程或用户线程。 * 当正在运行的线程都是守护线程时，Java 虚拟机退出。 该方法必须在启动线程前调用。  *  */public class ThreadDaemonDemo {    public static void main(String[] args) {        ThreadDaemon td1 = new ThreadDaemon();        ThreadDaemon td2 = new ThreadDaemon();         td1.setName("zhangsan");        td2.setName("lisi");         // 设置收获线程        td1.setDaemon(true);        td2.setDaemon(true);         td1.start();        td2.start();        Thread.currentThread().setName("wuyudong");        for (int x = 0; x < 5; x++) {            System.out.println(Thread.currentThread().getName() + ":" + x);        }    }}

5、中断线程

public final void stop()

public void interrupt()

import java.util.Date; public class ThreadStop extends Thread {    @Override    public void run() {        System.out.println("开始执行：" + new Date());         // 我要休息10秒钟        try {            Thread.sleep(10000);        } catch (InterruptedException e) {            // e.printStackTrace();            System.out.println("线程被终止了");        }         System.out.println("结束执行：" + new Date());    }}/* * public final void stop():让线程停止，过时了，但是还可以使用。 * public void interrupt():中断线程。 把线程的状态终止，并抛出一个InterruptedException。 */public class ThreadStopDemo {    public static void main(String[] args) {        ThreadStop ts = new ThreadStop();        ts.start();         // 超过三秒不醒过来，就干掉你        try {            Thread.sleep(3000);            // ts.stop();            ts.interrupt();        } catch (InterruptedException e) {            e.printStackTrace();        }    }}
