Sorry, do not expect people to go through your whole code 400lines is lots of reading. You better tell us which method should throw IOException so we can get on with it...

Open project in NetBeans IDE, or add throws clause manually.

Dude next time be more specific

if you want to specify that a method throws an exception use this:

public void someIOCode() throws IOException{
   "do some thing silly here"
}

if you want to intentionally throw an expception from a method use this:

public void someIOCode() throws IOException{
   throw new IOException("just fooling you");
}

How to put throws IOException in tis code statement? help..
