JAVA線程學習（二），java線程學習

JAVA線程學習（二），java線程學習
這是一個曉得項目共有三個類
第一個：
package com;


//軍隊線程
//類比作戰雙方的行為
public class ArmyRunnable implements Runnable {

//volatile保證了線程可以正確的讀取其他線程寫入的值
//可見度
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()+ "進攻對方["+ i +"]");
//讓出了處理器的時間下一次該誰進攻還不一定呢
Thread.yield();
}
}
System.out.println(Thread.currentThread().getName()+ "結束戰鬥！");
}



}
第二個：
package com;
/*
 * 隋唐演義大戲舞台
 * */
public class Stage extends Thread {


public void run(){
System.out.println("歡迎觀看隋唐演義！");
try {
Thread.sleep(5000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.out.println("大幕徐徐拉開");
try {
Thread.sleep(5000);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}

System.out.println("話說隋朝末年，隨軍與農民起義軍殺的昏天黑地。。。。");
ArmyRunnable armyTaskOfSuiDynastry = new ArmyRunnable();
ArmyRunnable armyTaskOfRevolt = new ArmyRunnable();

//使用Runnable介面建立線程
Thread armyOfSuiDynastry = new Thread(armyTaskOfSuiDynastry, "隨軍");
Thread armyOfRevolt = new Thread(armyTaskOfRevolt, "農民起義軍");

//啟動線程讓軍隊開始作戰
armyOfSuiDynastry.start();
armyOfRevolt.start();


//舞台線程休眠，大家專心觀看軍隊的廝殺
try {
Thread.sleep(50);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("正當雙方激戰正酣， 半路殺出個程咬金");
Thread mrCheng = new KeyPersonThread();
mrCheng.setName("程咬金");
System.out.println("程咬金的理想就是結束戰鬥， 是百姓安居樂業！");
armyTaskOfSuiDynastry.keepRunning = false;
armyTaskOfRevolt.keepRunning = false;

try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

/*
* 曆史大戲留給關鍵人物
* */
mrCheng.start();



//萬眾矚目，所有線程等待先生完成曆史使命
try {
mrCheng.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

System.out.println("戰爭結束，人民安居樂業，程先生實現了積極地人生夢想，為人民做出了貢獻");
System.out.println("表演結束，再見");
}
public static void main(String[] args) {
// TODO Auto-generated method stub
new Stage().start();


}


}
第三個：package com;


public class KeyPersonThread extends Thread {

public void run(){
System.out.println(Thread.currentThread().getName() + "開始戰鬥了！");
for(int i = 0; i < 10; ++i){
System.out.println(Thread.currentThread().getName() + "左突右殺， 攻擊隨軍！");
}
System.out.println(Thread.currentThread().getName() + "戰鬥結束了！");
}


}
