第1题:

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();

Mutex mutexY = new Mutex();

AthreadA = new A(mutexX,mutexY);

B threadB = new B (4);

threadA.(5);

threadB.start();

}

}


正确答案:(1)Thread
(1)Thread 解析:从下面的程序不难看出,类A、B均是线程类,因此需要继承自类Thread。

B. The author's father had fought in the First World War.

C. The author's father had fought in the Second World War.

D. The author's father threw two chairs on the fire to keep it going.


正确答案:B
42.文章最后一段第二行,作者说他的父亲曾经参加过第一次世界大战。但并未提及他是否参加了“二战”。选项 B是正确的。

第7题:

执行下列程序,显示的结果是______。

first="china"

second=""

a=LEN(first)

i=a

DO WHILE i>=1

second=second+SUBSTR(first,i,1)

i=i-1

ENDDO

?second


正确答案:anihc
anihc 解析:变量a使用LEN函数取得字符串变量first的长度,该变量包含5个字母,所以它的长度为5,即a=5,然后将a的值赋给i,那么i也等于5。使用一个DO WHILE循环语句来操作,判断条件是变量i是否大于等于0,如果小于0,则退出循环,否则执行循环体。此时SUBSTR(first,5,1)的值为a,(从“china”字符串的第5位开始取一位字符);执行i=i-1后,i=4,重复此循环体的操作,变量second的值依次为a、an、ani、anih,anihc,最后i0,退出循环体。

第8题:

PublicclassHoltextendsThread{PrivateStringsThreadName;Publicstaticvoidmain(Stringargv[]){Holth=newHolt();h.go();Holt(){};Holt(Strings){sThreadName=s;PublicStringgetThreadName(){returnsThreadName;}}Publicvoidgo(){Hotfirst=newHot("first");first.start();Hotsecond=newHot("second");second.start();}Publicvoidstart(){For(inti=0;i<2;i++){System.out.print(getThreadName()+i);Try{Thread.sleep(100);}catch(Exceptione){System.out.print(e.getMessage());}}}}当编译运行上面代码时,将会出现()

A.编译时错误

B.输出first0,second0,first0,second1

C.输出first0,first1,second10,second1

D.运行时错误


参考答案:C

第9题:

下面程序的输出结果是______。 include using namespace std; int x; void funA(int&am

下面程序的输出结果是______。

include<iostream>

using namespace std;

int x;

void funA(int&,int);

void funB(int,int&);

int main()

{

int first;

int second=5;

x=6;

funA(first,second);

funB(first,second);

cout<<first<<””<<second<<””<<x<<endl;

return 0;

}

void funA(int &a,int b)

{

int first;

first=a+b;

a=2*b;

b=first+4;

}

void funB(int u, int &v)

{

int second;

second=x;

v=second+4;

x=u+v;

}


正确答案:10 10 20
10 10 20 解析:本题考核函数的引用传递。“引用”实际上是给一个已知变量起个别名,对引用的操作也就是对被它引用的变量的操作。函数funA的功能是将第二个实参的值乘以2再赋值给第一个实参(通过引用传递实现),函数funB的功能是将全局变量x加上4再赋值给第二个实参,同时x等于第一个实参与第二个实参相加的和。
