testthread.java

里面所含源码是本人平时做程序的一些实例

public class TestThread
{
	public static void main(String args[])
	{
		Thread t=new ThreadDemo(20);
		t.start();
		Thread t2=new ThreadDemo(200);
		t.setName("线程1");
		t2.setName("线程2");
		//t2.setDaemon(true);
		
		
		try
		{
			t.join();
		}
		catch(InterruptedException ie){ie.printStackTrace();};
		t2.start();
		for(int i=0;i<50;i++)
		{
			System.out.println(Thread.currentThread().getName());
		}
		System.out.print("主线程结束!");
	}
}
class ThreadDemo extends Thread
{
	int n;
	public ThreadDemo(int n)
	{
		this.n=n;
	}
	public void run()
	{
		for(int i=0;i<n;i++)
		{
			System.out.println(this.getName()+":"+i);
		}
		System.out.println("线程结束:"+this.getName());
	}
	
}
