runnabledemo.java

我学习JAVA时的一些练习,可以供初学者使用

public class RunnableDemo implements Runnable
{
	String threadName;
	public RunnableDemo(String s)
	{
		System.out.println("Making thread"+s);
		threadName=s;
	}
	
	public void run()
	{
		for (int i=0;i<3;i++)
		{
			System.out.println("Running thread number="+threadName);
			try
			{
				Thread.sleep((int)(Math.random()*1000));
			}
			catch(InterruptedException e)
			{
				System.out.println(e.toString());
			}
		}
	}
	public static void main(String[] args)
	{
		String download="downloading";
		String play="plgying";
		Thread downloadThread,playThread;
		
		downloadThread=new Thread(new RunnableDemo(download));
		playThread=new Thread(new RunnableDemo(play));
		
		downloadThread.start();
		playThread.start();
		System.out.println("End of main");
	}
}
