java实现文件复制

import java.io.*;
public class ReadWriteFile{
public static void main(String [] args){
  try{
   File read = new File("c:\\test1.txt");
   File write = new File("c:\\test2.txt");
   BufferedReader br = new BufferedReader(new FileReadder(read));
   BufferedWriter bw = new BufferedWriter(new FileWriter(write));
   String temp =null;
   temp=br.readLine();
   while(temp!=null){
     //写文件,只适用与windows系统
      bw.write(temp+"\r\n");
     //继续写文件
      temp = br.readLine();
    
  }
   bw.close();
   br.close();
}catch(FileNotFoundException fe){
    System.out.println(fe.getMessage());
    fe.printStackTrace();
  }catch(Exception e){
     System.out.println(e.getMessage());
     e.printStackTrace();
  }
}
}
