阅读以下说明和Java代码，将应填入(n)处的字句写在对应栏内。
【说明】
下面的Java程序演示了程序竞争资源(Mutex的实例对象)而引起程序死锁的一种例子。
【Java程序】
import java．applet．*；
import java．awt．*；
//此处声明一个互斥类
class Mutex { }
class A extends (1)
{
private Mutex first，second；
public A(Mutex f，Mutex s)
{
first = f；
second = s；
}
public void run()
{
//锁定first变量
(2) (first)
{
try
{ //本线程挂起，等待重新调度
Thread．sleep(1)； //注意此处(1)不是小题序号
}
catch(InterruptedException e){}
System. out. println("threadA got first mutex")；
(2) (second) //锁定second变量
{ //do something
System. out. println("threadA got second mutex")；
} //释放second变量
} //释放first变量
}
}
class B extends (1)
{
private Mutex first，second；
public B(Mutex f，Mutex s)
{
(3) ；
second = s；
}
public void run()
{
(2) (second) //锁定second变量
{
//do something
try
{
Thread．sleep(((int)(3*Math．random()))*1000)；
//本线程挂起，等待重新调度
}
catch(InterruptedException e){}
System．out．println("threadB got second mutex")；
(2) (first) //锁定first变量
{
//do something
System．out．println("threadB got first mutex")；
} //释放first变量
} //释放second变量
}
}
public class DeadlockExample
{
public static void main(String arg[])
{
Mutex mutexX = new Mutex()；
