IOException cannot be resolved to a type

[Horrison2]

package com.org;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
public class IoTest {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

int i;
String s="";
try{

FileInputStream in=new FileInputStream("c:\\demo.txt");
FileOutputStream out=new FileOutputStream("c:\\demo1.txt");
try
{while((i=in.read())!=-1)
{
s=s+(char)i;
out.write(i);
}
}
catch (IOException e)
{
e.printStackTrace();
}
}
catch(FileNotFoundException e)
{
e.printStackTrace();
}
}
}


哪儿错了？

没错可以运行，输入输出流用完后记得关闭

先捕获FileNotFoundException然后才是IOException

import java.io.IOException; 少了个这个包
