JAVA将zip压缩文件解压
求一段代码，能将zip文件解压，效果如同正常使用的时候解压出来就行！急求！！！
[解决办法]

public static void unZip(String zipfile, String destDir) {
 
       destDir = destDir.endsWith( "//" ) ? destDir : destDir + "//" ;
       byte b[] = new byte [1024];
       int length;
 
       ZipFile zipFile;
       try {
           zipFile = new ZipFile( new File(zipfile));
           Enumeration enumeration = zipFile.getEntries();
           ZipEntry zipEntry = null ;
 
           while (enumeration.hasMoreElements()) {
              zipEntry = (ZipEntry) enumeration.nextElement();
              File loadFile = new File(destDir + zipEntry.getName());
 
              if (zipEntry.isDirectory()) {
                  // 这段都可以不要，因为每次都貌似从最底层开始遍历的
                  loadFile.mkdirs();
              } else {
                  if (!loadFile.getParentFile().exists())
                     loadFile.getParentFile().mkdirs();
 
                  OutputStream outputStream = new FileOutputStream(loadFile);
                  InputStream inputStream = zipFile.getInputStream(zipEntry);
 
                  while ((length = inputStream.read(b)) > 0)
                     outputStream.write(b, 0, length);
 
              }
           }
           System. out .println( " 文件解压成功 " );
       } catch (IOException e) {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
 
    }
 
}
