这是一个晓得项目共有三个类
第一个：
package com;
//军队线程
//模拟作战双方的行为
public class ArmyRunnable implements Runnable {
//volatile保证了线程可以正确的读取其他线程写入的值
//可见性
volatile boolean keepRunning = true;
@Override
public void run() {
// TODO Auto-generated method stub
while(keepRunning)
{
for(int i = 0; i < 5; ++i)
{
System.out.println(Thread.currentThread().getName()+ "进攻对方["+ i +"]");
//让出了处理器的时间下一次该谁进攻还不一定呢
Thread.yield();
}
}
System.out.println(Thread.currentThread().getName()+ "结束战斗！");
}
}
第二个：
package com;
/*
* 隋唐演义大戏舞台
* */
public class Stage extends Thread {
public void run(){
System.out.println("欢迎观看隋唐演义！");
try {
Thread.sleep(5000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("大幕徐徐拉开");
try {
Thread.sleep(5000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("话说隋朝末年，随军与农民起义军杀的昏天黑地。。。。");
ArmyRunnable armyTaskOfSuiDynastry = new ArmyRunnable();
ArmyRunnable armyTaskOfRevolt = new ArmyRunnable();
//使用Runnable接口创建线程
Thread armyOfSuiDynastry = new Thread(armyTaskOfSuiDynastry, "随军");
Thread armyOfRevolt = new Thread(armyTaskOfRevolt, "农民起义军");
//启动线程让军队开始作战
armyOfSuiDynastry.start();
armyOfRevolt.start();
//舞台线程休眠，大家专心观看军队的厮杀
try {
Thread.sleep(50);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("正当双方激战正酣， 半路杀出个程咬金");
Thread mrCheng = new KeyPersonThread();
mrCheng.setName("程咬金");
System.out.println("程咬金的理想就是结束战斗， 是百姓安居乐业！");
armyTaskOfSuiDynastry.keepRunning = false;
armyTaskOfRevolt.keepRunning = false;
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
/*
* 历史大戏留给关键人物
* */
mrCheng.start();
//万众瞩目，所有线程等待先生完成历史使命
try {
mrCheng.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("战争结束，人民安居乐业，程先生实现了积极地人生梦想，为人民做出了贡献");
System.out.println("表演结束，再见");
}
public static void main(String[] args) {
// TODO Auto-generated method stub
new Stage().start();
}
}
第三个：
package com;
public class KeyPersonThread extends Thread {
public void run(){
System.out.println(Thread.currentThread().getName() + "开始战斗了！");
for(int i = 0; i < 10; ++i){
System.out.println(Thread.currentThread().getName() + "左突右杀， 攻击随军！");
}
System.out.println(Thread.currentThread().getName() + "战斗结束了！");
}
}
