mode     the mode in which the file is to be opened

charset     the charset to be used to decode the ZIP entry name and comment that are not encoded by using UTF-8 encoding (indicated by entry's general purpose flag).

Exceptions:

ZipException     if a ZIP format error has occurred

IOException     if an I/O error has occurred

SecurityException     if a security manager exists and its checkRead method doesn't allow read access to the file,or its checkDelete method doesn't allow deleting the file when the OPEN_DELETE flag is set
