threadtest.java

java课程的资料以及实验的代码

class ThreadTest implements Runnable
{ 
	Thread t1,t2;
	public ThreadTest()
	{ 
		t1=new Thread(this);
		t1.start();
		t2=new Thread(this);
		t2.setDaemon(true);
	}
	public void run()
	{ 
		System.out.println("激活的线程数："+Thread.activeCount());
		
		System.out.println("t1的名称："+t1.getName());
		t1.setName("huhu");
		System.out.println("t1修改后的名称："+t1.getName());
		System.out.println("");
		System.out.println("t1是否精灵线程："+t1.isDaemon());
		System.out.println("t2的名称："+t2.getName());
		System.out.println("t2是否精灵线程："+t2.isDaemon());	
			
		System.out.println("t1是否激活："+t1.isAlive());
		
	}
	public static void main(String[] args)
