下列程序的功能是在控制台上,每隔1秒钟显示字符串"Hello",能够填写在程序中下划线位置,使程序完整,并能够正确运行的语句是()
public class Test implements Runnable{
public static void main(String[] args){
Test t=new Test();
Thread tt=new Thread(t);
tt.start();
}
public void run(){
for(;;){
try{ __________ }catch(_________ e ){}
System.out.println(“Hello”);
}
}
}
Thread.sleep (1000), InterruptedException
sleep (1000), InterruptedException
t.sleep (1000), InterruptedException
Thread.sleep (1000), RuntimeException
