實驗4java網(wǎng)絡(luò)編程基礎(chǔ)

1、實驗四 網(wǎng)絡(luò)編程基礎(chǔ)一、實驗?zāi)康模?、掌握InetAddress類的使用。2、掌握URL類的使用和概念。3、掌握URLConncetion類的使用和概念。二、實驗內(nèi)容：1、使用InetAddress類的方法獲取/的主機的IP地址。2、使用InetAddress類的方法獲取本地機的名稱和IP地址。3、運行下面的程序，掌握獲取URL信息的一些方法。import .*;import java.io.*; class URLTest public static void main(String args)tryURL url=new URL(http:/localhost:8080/);System.

2、out.println(文件名:+url.getFile();System.out.println(主機名:+url.getHost();System.out.println(端口號:+url.getPort();System.out.println(協(xié)議名:+url.getProtocol();catch(MalformedURLException e)e.printStackTrace();注意：需要先啟動tomcat。4、編程實現(xiàn)利用URL類獲取網(wǎng)絡(luò)資源的程序。import .*;import java.io.*;public class URLRead public static vo

3、id main(String args) throws Exception URL web = new URL(:8080);BufferedReader in = new BufferedReader(new InputStreamReader(web.openStream();String inputLine;while (inputLine = in.readLine() != null)System.out.println(inputLine);in.close();5. 利用URLConnection對URL資源的讀取編寫KY12_3.java 程序文件，源代碼如下。import .

4、*; import java.io.*; public class URLConnectionReader public static void main(String args) throws Exception URL web = new URL(:8080); URLConnection webc=web.openConnection(); /get an instance of URLConnection BufferedReader in = new BufferedReader(new InputStreamReader( webc.getInputStream(); /use o

5、f URLConnection String inputLine; while (inputLine = in.readLine() != null) System.out.println(inputLine); in.close(); 編譯并運行6. 掌握URLConnection對URL資源的寫入編寫KY12_4.java 程序文件，源代碼如下。import java.io.*;import .*; class Reverse public static void main(String args) throws Exception URL url = new URL(http:/loca

6、lhost:8080/a/a.jsp);URLConnection connection = url.openConnection();connection.setDoOutput(true);OutputStreamWriter out = new OutputStreamWriter( connection.getOutputStream();out.write(sid=4);out.flush();out.close();BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream();String decodedString;while (decodedString = in.readLine() != null) System.out.println(decodedString);in.close(); 編譯并運行注意 需要在tomcat安裝目錄下的webapps目錄下建立a目錄并放入a.jsp文件。實驗報告內(nèi)容：編寫程
