上机题目（0基础）- Java网络操作-打印网页（Java）

打印一个网页，熟悉Java网络编程：import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.MalformedURLException;

import java.net.URL;

import java.net.URLConnection;

public class URLReader {

public static void main(String[] args) {

System.out.println(getContent());

}

private static String getContent(){

InputStream in=null;

URLConnection connection=null;

InputStreamReader readerStream=null;

StringBuffer resultBuffer = new StringBuffer();

BufferedReader readerBuff=null;

try {

URL url=new URL("http://www.baidu.com");

connection = url.openConnection();

in=connection.getInputStream();

readerStream=new InputStreamReader(in);

readerBuff=new BufferedReader(readerStream);

String temp=null;

while((temp=readerBuff.readLine())!=null){

resultBuffer.append(temp+"\n");

}

if (in!=null) {

in.close();

}

if (readerStream != null) {

readerStream.close();

}

if (readerBuff != null) {

readerBuff.close();

}

} catch (MalformedURLException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return resultBuffer.toString();

}

}

执行将打印整个网页的源码
