filecopy.java

这个是学习网络编程的好好文档！ 里面有一些老师发给的学习jsp的课件！

import java.io.*;
public class FileCopy
{
  public void copy(String source,String target)
  {
    FileInputStream from;
    FileOutputStream to;
    int i;
    try
    {
      from = new FileInputStream(source);
      to = new FileOutputStream(target);
      while((i=from.read())!=-1) to.write(i);
      from.close();
      to.close();
      System.out.println("复制完成!");
    }
    catch(IOException ex)
    {
      System.err.println("复制操作失败!");
    }
  }
  public static void main(String[] args)
  {
    FileCopy fc = new FileCopy();
    fc.copy(args[0],args[1]);
  }
}
