java多线程例子

第一个例子

package timeprinter;

import java.util.Date;

public class TimePrinter implements Runnable {

	int pauseTime;
	String name;

	public TimePrinter(int x, String n) {
		pauseTime = x;
		name = n;
	}

	/**
	 * @param args
	 *            当使用 runnable 接口时，您不能直接创建所需类的对象并运行它；必须从 Thread 类的一个实例内部运行它
	 * 
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		// TimePrinter tp1 = new TimePrinter(1000, "Fast Guy"); 继承Thread
		// tp1.start();
		// TimePrinter tp2 = new TimePrinter(3000, "Slow Guy");
		// tp2.start();
		Thread t1 = new Thread(new TimePrinter(1000, "Fast Guy"));
		t1.start();
		Thread t2 = new Thread(new TimePrinter(3000, "Slow Guy"));
		t2.start();
	}

	private void start() {
		this.run();
	}

	@Override
	public void run() {
		while (true) {
			try {
				System.out.println(name + ":"
						+ new Date(System.currentTimeMillis()));
				Thread.sleep(pauseTime);
			} catch (Exception e) {
				System.out.println(e);
			}
		}

	}

}

程序一直不停的执行，结果如下：
Fast Guy:Thu Aug 19 16:13:55 GMT+08:00 2010
Slow Guy:Thu Aug 19 16:13:55 GMT+08:00 2010
Fast Guy:Thu Aug 19 16:13:56 GMT+08:00 2010
Fast Guy:Thu Aug 19 16:13:57 GMT+08:00 2010
Slow Guy:Thu Aug 19 16:13:58 GMT+08:00 2010
。。。

public class TestMitiThread {
    public static void main(String[] rags) {
        System.out.println(Thread.currentThread().getName() + " 线程运行开始!");
        new MitiSay("A").start();
        new MitiSay("B").start();
        System.out.println(Thread.currentThread().getName() + " 线程运行结束!");
    }
}
 
class MitiSay extends Thread {
    public MitiSay(String threadName) {
        super(threadName);
    }
 
    public void run() {
        System.out.println(getName() + " 线程运行开始!");
        for (int i = 0; i < 10; i++) {
            System.out.println(i + " " + getName());
            try {
                sleep((int) Math.random() * 10);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println(getName() + " 线程运行结束!");
    }
}
