5、继承时候类的执行顺序问题,一般都是选择题,问你将会打印出什么? 答:父类： package test;
public class FatherClass { public FatherClass() {
System.out.println(\ } }
?Copyleft;2008-10-01; by feeling.
23
子类:
package test;
import test.FatherClass;
public class ChildClass extends FatherClass { public ChildClass() {
System.out.println(\ }
public static void main(String[] args) { FatherClass fc = new FatherClass(); ChildClass cc = new ChildClass(); } }
输出结果：
C:>java test.ChildClass FatherClass Create FatherClass Create ChildClass Create
6、内部类的实现方式? 答：示例代码如下： package test;
public class OuterClass { private class InterClass { public InterClass() {
System.out.println(\ } }
public OuterClass() {
InterClass ic = new InterClass();
System.out.println(\ }
public static void main(String[] args) { OuterClass oc = new OuterClass(); } }
输出结果:
C:>java test/OuterClass InterClass Create OuterClass Create
7、再一个例题： public class OuterClass { private double d1 = 1.0; //insert code here
?Copyleft;2008-10-01; by feeling.
24
}
You need to insert an inner class declaration at line 3. Which two inner class declarations are valid?(Choose two.) A. class InnerOne{
public static double methoda() {return d1;} }
B. public class InnerOne{
static double methoda() {return d1;} }
C. private class InnerOne{ double methoda() {return d1;} }
D. static class InnerOne{
protected double methoda() {return d1;} }
E. abstract class InnerOne{
public abstract double methoda(); }
说明如下：
一.静态内部类可以有静态成员，而非静态内部类则不能有静态成员。 故 A、B 错 二.静态内部类的非静态成员可以访问外部类的静态变量，而不可访问外部类的非静态变量；return d1 出错。故 D 错
三.非静态内部类的非静态成员可以访问外部类的非静态变量。 故 C 正确 四.答案为C、E
8、Java 的通信编程，编程题(或问答)，用JAVA SOCKET编程，读服务器几个字符，再写入本地显示？
答:Server端程序: package test; import java.net.*; import java.io.*; public class Server { private ServerSocket ss; private Socket socket; private BufferedReader in; private PrintWriter out; public Server() { try {
ss=new ServerSocket(10000); while(true) {
socket = ss.accept();
String RemoteIP = socket.getInetAddress().getHostAddress(); String RemotePort = \
System.out.println(\
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
