how to handle filenotfoundexception in java

It will throw a FileNotFoundException if the file doesn't 
exist and cannot be created (doc), but it will create it if it can. 
To be sure you probably should first test that the file exists before 
you create the FileOutputStream (and create with createNewFile() if 
it doesn't)
