Look up the information on the Internet, there is a saying is the problem of coding, see how the Foreigner said, reference, is really the problem of coding. Attach my partial uncompressed code

public static void Unzip (string zipfilepath, String TargetPath) throws IOException {OutputStream OS =
        Null
        InputStream is = null;
        ZipFile zipfile = null;
            try {zipfile = new ZipFile (Zipfilepath,charset.forname ("GBK"));
            String directorypath = ""; if (null = = TargetPath | | "". Equals (TargetPath)) {directorypath = zipfilepath.substring (0, Zipfilepath. Las
            Tindexof ("."));
            else {directorypath = TargetPath;
            } enumeration<?> Entryenum = Zipfile.entries ();
                if (null!= entryenum) {zipentry zipentry = null;
                    while (Entryenum.hasmoreelements ()) {ZipEntry = (zipentry) entryenum.nextelement (); if (zipentry.getsize () > 0) {//files file TargetFile = Fileutil.buil
       Dfile (DirectoryPath                         + File.separator + zipentry.getname (), false);
                        OS = new Bufferedoutputstream (new FileOutputStream (targetfile));
                        is = Zipfile.getinputstream (zipentry);
                        byte[] buffer = new byte[4096];
                        int readlen = 0;
                            while ((Readlen = is.read (buffer, 0, 4096)) >= 0) {os.write (buffer, 0, Readlen);
                        Os.flush ();
                        } is.close ();
                    Os.close (); } if (Zipentry.isdirectory ()) {String pathtemp = DirectoryPath + File.separato
                    	R + zipentry.getname ();
                    	File File = new file (pathtemp);
                        File.mkdirs ();
System.out.println (pathtemp);
                    Continue
     }           The catch (IOException ex) {throw ex;
                finally {if (null!= zipfile) {zipfile.close ();
            ZipFile = null;
            } if (null!= is) {is.close ();
            } if (null!= OS) {os.close (); }
        }
    }

Statement:

ZipFile = new ZipFile (Zipfilepath,charset.forname ("GBK"));

Not all compression packages are encoded GBK, and special handling is required for different situations.
