Java【多线程知识总结(10)】线程通信之wait()与notify()的运用--模拟指挥官指挥2个连队交替轰炸战区<另外的写法>

我也粘贴一下另外一种写法..嘿嘿~~ 大家多交流多学习

图好玩,写来跑跑,Java基础,挺重要的,代码还是要多写啊

package TraditionalThread;public class ZhiHuiGuan{    public static void main(String args[])    {        new ZhiHuiGuan().call();    }    /**     * 轰炸命令启动     */    private void call()    {        final Army army = new Army();        new Thread(new Runnable()        {            @Override            public void run()            {                for (int i = 1; i <= 60; i++)                {                    army.A(i);                }            }        }).start();                for (int i = 1; i <= 60; i++)        {            army.B(i);        }    }}class Army{    /**     * A连轰炸/B连熄火     */    private boolean isAFire = true;        /**     * A连轰炸任务     */    public synchronized void A(int taskCount)    {        if (!isAFire)        {            //ShowTime For B连. A连休息            try{this.wait();} catch (InterruptedException e){}        }            for (int i = 1; i <= 12; i++)            {                try{Thread.sleep(50);}catch (Exception e){}                System.out.println("A连正在进行第"+taskCount+"次任务,正在发射第"+(i)+"枚导弹");            }            //A连轰炸完毕,通知B连的兄弟开火            isAFire = false;            this.notify();    }        /**     * B连轰炸任务     */    public synchronized void B(int taskCount)    {        if (isAFire)        {            //ShowTime For A连. B连休息            try{this.wait();} catch (InterruptedException e){}        }            for (int j = 1; j <= 30; j++)            {                try{Thread.sleep(50);}catch (Exception e){}                System.out.println("B连正在进行第"+taskCount+"次任务,正在发射第"+(j)+"枚导弹");            }            //B连轰炸完毕,通知A连的兄弟开火            isAFire = true;            this.notify();    }}

其实如果用上并发库里的Lock更爽更简洁...一起进步

package TraditionalThread;import java.util.concurrent.locks.Lock;import java.util.concurrent.locks.ReentrantLock;public class ZhiHuiGuanHigh{    public static void main(String args[])    {        new ZhiHuiGuanHigh().call();    }    /**     * 轰炸命令启动     */    private void call()    {        final Army army = new Army();        new Thread(new Runnable()        {            @Override            public void run()            {                for (int i = 1; i <= 60; i++)                {                    army.A(i);                }            }        }).start();                for (int i = 1; i <= 60; i++)        {            army.B(i);        }    }}class ArmyHigh{    Lock lock = new ReentrantLock();    /**     * A连轰炸/B连熄火     */    private boolean isAFire = true;        /**     * A连轰炸任务     */    public void A(int taskCount)    {        if (!isAFire)        {            //ShowTime For B连. A连休息            lock.lock();        }            for (int i = 1; i <= 12; i++)            {                try{Thread.sleep(50);}catch (Exception e){}                System.out.println("A连正在进行第"+taskCount+"次任务,正在发射第"+(i)+"枚导弹");            }            //A连轰炸完毕,通知B连的兄弟开火            isAFire = false;            lock.unlock();    }        /**     * B连轰炸任务     */    public synchronized void B(int taskCount)    {        if (isAFire)        {            //ShowTime For A连. B连休息            lock.lock();        }            for (int j = 1; j <= 30; j++)            {                try{Thread.sleep(50);}catch (Exception e){}                System.out.println("B连正在进行第"+taskCount+"次任务,正在发射第"+(j)+"枚导弹");            }            //B连轰炸完毕,通知A连的兄弟开火            isAFire = true;            lock.unlock();    }}
