threadsynchronizdemo3.java

JAVA的一些基础教程

public class ThreadSynchronizDemo3{
	public void 写文件(String 内容){
		synchronized(this){
			System.out.println("进入写文件函数的线程:"+ Thread.currentThread().getName());
			System.out.println("获取当前对象:"+ this + "的锁");
				try{
					Thread.sleep(1000*5);
					System.out.println("线程:"+ Thread.currentThread().getName() + " 休息了5秒");
				}catch(Exception e){}
				for(int i=0; i< 内容.length(); i++)
					System.out.print(内容.charAt(i));
			System.out.println("\n退出写文件函数的线程:"+ Thread.currentThread().getName() );
			System.out.println("释放当前对象:"+ this + "的锁\n");
		}
	}

	public void 创建两个线程(){
		Runnable r = new Runnable(){
			public void run(){
				写文件("学JAVA其实是件很容易的事，只要你用心学，花时间");
			}
		};

		Thread 线程A = new Thread(r,"线程A");
		Thread 线程B = new Thread(r,"线程B");
		线程A.start();
		线程B.start();
	}

	public static void main(String arg[]){
		ThreadSynchronizDemo3 demo = new ThreadSynchronizDemo3();
		demo.创建两个线程();
	}
}
