1.线程同步

package com.test.synchronizeds;//线程同步public class TraditionThreadSynchronized {    public void init(){        final Outputer o=new Outputer();                //线程1        new Thread(new Runnable() {            @Override            public void run() {                while(true){                    try {                        Thread.sleep(100);                    } catch (InterruptedException e) {                        e.printStackTrace();                    }                    o.output1("chenxiaobing");                }            }        }).start();                //线程2        new Thread(new Runnable() {            @Override            public void run() {                while(true){                    try {                        Thread.sleep(100);                    } catch (InterruptedException e) {                        e.printStackTrace();                    }                    o.output1("donyanxia");                }            }        }).start();    }    public static void main(String[] args) {        new TraditionThreadSynchronized().init();    }        static class Outputer{                //方法1        public void output1(String name){            int len=name.length();            synchronized(this){
   //钥匙必须相同 :synchronized中的的变量，必须是针对所有线程来讲都是一样的，此时才能打达到线程同步的效果.                for(int i=0;i

 2.线程同步、交互

package com.test.synchronizeds;/** * 子线程循环10次，主线程循环20次，子线程循环10次，主线程循环20次，如此交替循环50次 * @author Administrator * */public class TraditionThreadCommunication {        public static void main(String[] args) {        final Bussines b=new Bussines();                //子线程        new Thread(new Runnable() {            @Override            public void run() {                for(int i=1;i<=50;i++){                    b.sub(i);                }            }        }).start();                //主线程        for(int i=1;i<=50;i++){            b.main(i);        }    }        static class Bussines{        private boolean bshouldsub=true;        public synchronized void main(int loop){            while(bshouldsub){                try {                    this.wait();                } catch (InterruptedException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }            }            for(int i=1;i<=20;i++){                System.out.println("main thread sequece of"+i+" loop of"+loop);            }            bshouldsub = true;            this.notify();        }                public synchronized void sub(int loop){            while(!bshouldsub){                try {                    this.wait();                } catch (InterruptedException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }            }            for(int i=1;i<=10;i++){                System.out.println("sub thread sequece of"+i+" loop of"+loop);            }            bshouldsub = false;            this.notify();        }    }}
