How to read data using Runtime

I wrote the following program to read data from the required file during the runtime. But I'm unable to get any data.

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.io.IOException;

import java.io.File;

publicclass RunTime1

{

publicstaticvoid main(String args[])

{

Process p=null;

File filename=new File("RunTime1.java");

BufferedReader reader=null;

String[] cmdarray={"notepad",filename.getAbsolutePath()};

String line=null;

try{

p=Runtime.getRuntime().exec(cmdarray);

reader=new BufferedReader(new InputStreamReader(p.getInputStream()));

p.waitFor();

while((line=reader.readLine())!=null)

System.out.println(line+"-->");

}catch(IOException e){}

catch(InterruptedException ie){}

}

}

What's wrong with this program? Please answer me.
