| 请问一下复制文本以下两种方法,方法一的代码简单,方法二运用了流的缓冲区,哪种方法更好? 方法一
 import java.io.*;
 class One
 {
 public static void main(String[] args)
 {
 FileWriter fw = null;
 FileReader fr = null;
 try
 {
 fw = new FileWriter("000.txt");
 fr = new FileReader("Demo.java");
 char[] buf = new char[1024];
 int len = 0;
 while ((len=fr.read(buf))!=-1)
 {
 fw.write(buf,0,len);
 }
 }
 catch (IOException e)
 {
 throw new RuntimeException("读写失败");
 }
 finally
 {
 try
 {
 if (fw!=null)
 fw.close();
 }
 catch (IOException e)
 {
 throw new RuntimeException("写入关闭失败");
 }
 try
 {
 if (fr!=null)
 fr.close();
 }
 catch (IOException e)
 {
 throw new RuntimeException("读取关闭失败");
 }
 }
 }
 }
 
 方法二
 
 import java.io.*;
 class Two
 
 {
 public static void main(String[] args)
 {
 BufferedWriter bufw = null;
 BufferedReader bufr = null;
 
 try
 {
 bufw = new BufferedWriter(new FileWriter("000.txt"));
 bufr = new BufferedReader(new FileReader("Demo.java"));
 
 String line = null;
 while ((line=bufr.readLine())!=null)
 {
 bufw.write(line);
 bufw.newLine();
 bufw.flush();
 }
 }
 catch (IOException e)
 {
 throw new RuntimeException("读写失败");
 }
 finally
 {
 try
 {
 if (bufw!=null)
 bufw.close();
 }
 catch (IOException e)
 {
 throw new RuntimeException("写入关闭失败");
 }
 try
 {
 if (bufr!=null)
 bufr.close();
 }
 catch (IOException e)
 {
 throw new RuntimeException("读取关闭失败");
 }
 }
 
 
 
 
 
 
 }
 }
