In fact, the CAD/CAM system works as a common data base that is used for all the design and manufacturing jobs.

Word families are groups of words that share a common base to which different prefixes and suffixes are added. A: 正确 B: 错误

标准以太网指的是 ( ) A: 10 BASE 5 B: 10 BASE 2 C: 10 BASE T D: 100 BASE T

（6-2）定义如下Base类，能在(1)处正确调用Base的构造方法。 class Base{ int x,y; Base(int x){} Base(int x,int y){ //(1)调用Base的构造方法 } }

如何能使程序调用Base类的构造方法输出"base constructor"; class Base{ Base(int i){ System.out.println("base constructor"); } Base(){  } } public class Sup extends Base{ public static void main(String argv[]){ Sup s= new Sup(); //One } Sup() { //Two } public void derived() { //Three } }

给出下面的代码段 public class Base{ int x, y; static int z; public Base(int a,int b)<br/>{ x=a; y=b; } } 以下代码错误的是?(). A: Base b=new Base(); <br/>b.z=10; B: Base b=new Base(1,2); <br/>b.z=10; C: Base.z=10; D: Base b=new Base(1,2);<br/>b.x=2;

以下哪一项不是.NET框架体系结构的组成部分（）。 A: 公共语言运行时（Common Language Runtime，CLR） B: 统一类库（Base Class Library） C: ADO D: 活动服务器页面（AS E: NET）

Which transistor amplifier configuration is the most commonly used? A: common-emitter B: common-collector C: common-base D: None of these are used more often than the others.

（6-2）以下代码会出现编译错误。 class Base{ public Base () { System.out.println("1"); } public void Base () { System.out.println("2"); } }

以下代码调试结果 class Base {} class Sub extends Base {} public class CEx{ public static void main(String argv[]){ Base b = new Base(); Sub s = (Sub) b; } }
