Java implementation of compressed and uncompressed files

Due to the need to unzip the zip file, the investigation found that there are two open source Toolkit, one is the Apache Ant Toolkit, the other is the Java API comes with the toolkit However, there is a problem with the toolkit that comes with Java: if there are non-English characters (such as Chinese, Israeli) in the compressed or decompressed file, there will be a problem during the operation: Malformal eception ...

Here is the code for compression and decompression via Apache's Zip toolkit (requires Ant.jar):

The following is the code for the implementation of the compression and decompression toolkit implemented in the Java API under the Java.util.zip package (if the file name has a non-English encoding, there is a problem):

Package Testzip;import Java.io.file;import Java.io.fileoutputstream;import java.io.ioexception;import Java.io.inputstream;import Java.io.outputstream;import Java.util.enumeration;import Java.util.zip.ZipEntry;import            Java.util.zip.zipfile;import Org.apache.commons.io.ioutils;public class Ziptest {/** * Unzip it * * @param zipfile * Input zip file * @param output * Zip file output folder * @throws IOException */public static void UnZip  It (string file, String OutputFolder) throws IOException {ZipFile zipfile = new ZipFile (file); try {enumeration<? extends zipentry> entries = Zipfile.entries (); while (Entries.hasmoreelements ()) {ZipEntry entry = entries.nextelement (); File Entrydestination = new file (OutputFolder, Entry.getname ()), if (Entry.isdirectory ()) {entrydestination.mkdirs ();} else {entrydestination.getparentfile ().
