[Advanced-java] After Unzip delete that file programatically??

[Nikolaos Giannopoulos]

Your program makes little sense:

Q. What do you think file (which is for some odd reason a static) will
retain if it is changed with every iteration of this loop?

A. The last file object that was created!

<snip>
> Enumeration entries = zip.entries();
> for ( int i = 0; entries.hasMoreElements(); ) {
> ZipEntry entry = (ZipEntry) entries.nextElement();
> monitor.setNote(entry.getName());
> file = new File(outputDir, entry.getName());
<snip>
> }


Q. What do you think your going to delete here?

A. At best if your program works - the last unzipped file ONLY and NOT the
zipped file itself as the file object that refers to it is long gone.

> file.delete();


If you want to write a utilities type class then don't retain static
attributes and simply call a single method that does what you want i.e.
hint: your unzip method signature could look like this:

public static void unzip(
    String rootDir, File zipFile, boolean deleteZipOnExit)
