Hi all,

I am currently developing a java application that uses a CSV file
which it reads and then populates the items inside a JList. Then the
user is able to delete an item from JList which then writes the
information to a temporary file. Once the data has been written I then
want the original file that it read in to be deleted. However for some
reason it keeps on failing and saying the deletion failed but I do not
understand. Below is the code that I am using in order for the item to
be removed from the JList and then written a the file with the new
information and also with the function where it is deleting the file:

    public void deleteOldFile() {

           try {
              File file = new File("C:\\Documents and Se=

ttings\\All Users\

\Application Data\\Remote Shutdown\\ExceptionsList.csv");

If you create a separate String for the file name there is always a
chance that you have mistyped it in one place. I'd pass the file name or
a File instance as a parameter of deleteOldFile(); Alternatively I'd
define it as a constant and use it everywhere something is done with
that file.

boolean success = file.delete();

before this I might try
    if (!file.exists()) {
       System.out.println("File '" + file + "' does not exist");
       System.exit(1); // or whatever
    }
    if (!file.isFile()) {
       System.out.println("File '" + file + "' is not a normal fil=

e");

       System.exit(1); // or whatever
    }
    etc etc

if (!success){
System.out.println("Deletion failed.");

Thanks for the help. I resolved this issue. Found out I don't need to
create a temp file and then delete the old file instead just overwrite
the existing file is perfect for what I need.

Thank you
