各位大侠,帮小弟看看这段代码怎么了?

import java.util.*;
import java.io.*;
class CFileExample2
{
private String s="";
private RandomAccessFile f1=new RandomAccessFile("file1.txt","rw");
private RandomAccessFile f2=new RandomAccessFile("file2.txt","rw");
void fileLink()
{
  s=f1.readLine()+f2.readLine();
  char c[]=s.toCharArray();
  Arrays.sort(c);
  FileOutputStream out=new FileOutputStream("new.txt");
  for(int i=0;i<c.length;i++)
  {
   out.write(c[i]);
  }
  out.close();
  f1.close();
  f2.close();
}
}
public class FileExample2
{
public static void main(String[] args)throws IOException
  {
  CFileExample2 f=new CFileExample2();
  f.fileLink();
  }
}
FileExample2.java:6: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown
private RandomAccessFile f1=new RandomAccessFile("file1.txt","rw");
^
FileExample2.java:7: unreported exception java.io.FileNotFoundException; must be caught or declared to be thrown
private RandomAccessFile f2=new RandomAccessFile("file2.txt","rw");
^

我的file1.txt各file2.txt文件都在同一文件夹下,并且每个文件只有一行字母而已。我觉得我的声明没有错的嘛?why?
