How can I get:
java.util.zip.ZipException ZIP_Read: error reading zip file?
I've tried with different corrupted zips, corrupted jars, but no luck so far. Any idea?

A bad header? Try overwriting the first four bytes of a zip file with random values – g00se May 19 '22 at 14:02

@g00se That'll just give you an error about corrupt local header (the real "header" of a zip file is at the end - a fact I didn't know before GIFAR). This error sounds like a problem with the underlying read - so truncation, remote storage failure or perhaps deletion of the file may do the trick. – Tom Hawtin - tackline May 19 '22 at 16:35

Done ;) FYI: Finally I got this exception on opening an empty ZIP file. Thanks, Guys! – gonzo33 May 19 '22 at 19:18

private void play() {
try {
ZipFile zipFile = new ZipFile("./data/demo.zip");
ZipArchiveEntry zipArchiveEntry;
Enumeration<ZipArchiveEntry> entries = zipFile.getEntries();
while (entries.hasMoreElements()) {
zipArchiveEntry = entries.nextElement();
long size = zipArchiveEntry.getSize();
// more code
}
} catch(Exception e) {
e.printStackTrace();
}
}
