java多线程之Lock线程同步

1、线程同步：

package cn.itcast.heima2;

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;


public class LockTest {

    /**
     * @param args
     */
    public static void main(String[] args) {
        new LockTest().init();
    }
    
    private void init(){
        final Outputer outputer = new Outputer();
        new Thread(new Runnable(){
            @Override
            public void run() {
                while(true){
                    try {
                        Thread.sleep(10);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    outputer.output("zhangxiaoxiang");
                }
                
            }
        }).start();
        
        new Thread(new Runnable(){
            @Override
            public void run() {
                while(true){
                    try {
                        Thread.sleep(10);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    outputer.output("lihuoming");
                }
                
            }
        }).start();
        
    }

    static class Outputer{
        Lock lock = new ReentrantLock();
        public void output(String name){
            int len = name.length();
            lock.lock();
            try{
                for(int i=0;i<len;i++){
                    System.out.print(name.charAt(i));
                }
                System.out.println();
            }finally{
                lock.unlock();
            }
        }
    }
}
