刘艺编著的java教程的课本习题加例题代码 很有用哦！

import java.io.*;
public class FileIn_Out{
  public static void main(String args[]){
   try{
    FileInputStream rf=new  FileInputStream("d:\\datafile\\file1.txt");
    FileOutputStream wf=new FileOutputStream("d:\\datafile\\file2.txt");
    byte b[]=new byte[512];
    while((rf.read(b,0,512))!=-1)
      wf.write(b);
    rf.close();
    wf.close();
   }
   catch(IOException ie){
    System.out.println(ie);
   }
   catch(Exception e){
    System.out.println(e);
   }
 }
