上機題目（初級）- Java網絡操作-打印網頁（Java）

打印一個網頁，熟悉Java網絡編程：

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();  

}
	}
