java如何解压缩rar文件？

Answer 1

// Decompress a zip file to a specific dir
   public String doUnzip(String sourceFileName, String targetFolderName) throws FileNotFoundException, IOException
   {
         String targetName = null;
         if (!targetFolderName.endsWith("/") || !targetFolderName.endsWith("\\"))
         {
               targetName = targetFolderName.replace('\\', '/');
               targetName = targetFolderName + "/" +"temp" +"/" ;
               System.out.println("File targetName is "+targetName);
         }         sourceFileName = sourceFileName.replace('\\', '/');         try
         {
               File tmpDirFile = new File(targetName);
               if (!tmpDirFile.exists())
                  tmpDirFile.mkdirs();               ZipFile zipFile = new ZipFile(sourceFileName);
               ZipEntry zipEntry = null;               byte[] buffer = new byte[4096];
               int bytesRead = 0;               for (Enumeration fileLists = zipFile.entries(); fileLists.hasMoreElements(); )
               {
                 String fileName = fileLists.nextElement().toString();
                // System.out.println("Element is " + fileName);
                 File scriptFile = new File(targetName + fileName);                 if (!fileName.endsWith("/"))
                 {
                         scriptFile.getParentFile().mkdirs();
                         System.out.println("UNZIP: " + scriptFile.getPath());                         zipEntry = new ZipEntry(fileName);                         BufferedInputStream bufferFileIn = new BufferedInputStream(zipFile.getInputStream(zipEntry));
                         FileOutputStream outputStream = new FileOutputStream(scriptFile);                        while ( (bytesRead = bufferFileIn.read(buffer)) > 0)
                               outputStream.write(buffer, 0, bytesRead);                        bufferFileIn.close();
                        outputStream.close();
                 }               }
               zipFile.close();             }
             catch(IOException ioErr)
             {
                 System.out.println("Decompress file fail");
                 ioErr.printStackTrace();
             }        //look tcl file and write suite file
           return targetName;   }

JAVA中，只能创建一个zip压缩文件。
如果是rar的话，好像没有这个api。
另外人家rar的算法也不会公开出来的

其实就用zip多好呀，
还支持linux
