URL创建了字节输入流，字符输入流，缓冲字符流，可是只有缓冲字符流输出是正确的？

package TestOfSocket;

import java.net.*;

import java.io.*;

public class TestOfIO {

	public static void main(String[] args) 

	{

		try{

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

			InputStream in=url.openStream();

			InputStreamReader inr=new InputStreamReader(in);



			System.out.println("*******************");

			byte[] buffer1=new byte[10];

			in.read(buffer1,0,buffer1.length);

			System.out.println(buffer1.toString());



			System.out.println("*******************");

			char[] chara=new char[30];

			inr.read(chara,0,chara.length);

			System.out.println(chara.toString());



			BufferedReader buffer=new BufferedReader(inr);

			String data=buffer.readLine();

			while(data!=null){

				System.out.println(data);

				data=buffer.readLine();

			}

			buffer.close();

			inr.close();

			in.close();

		}

		catch(MalformedURLException e)

		{

			e.printStackTrace();

		}

		catch(IOException e)

		{

			e.printStackTrace();

		}

	}

}
