public  void unzip(string zipfilepath, string destdir, string flname) throws exception      {      int buffer = 2048;//buffer size  try       {         file dir = new file(destdir);         // throw exception if output directory doesn't exist          if(!dir.exists())          {             //print message in consol         system.out.println("no destination directory exists unzip operation.");         throw new exception();                 }          bufferedoutputstream dest = null;          bufferedinputstream = null;          zipentry entry;          zipfile zipfile = new zipfile(zipfilepath);          enumeration e = zipfile.entries();          while(e.hasmoreelements())           {             entry = (zipentry) e.nextelement();             system.out.println("extracting: " +entry);             = new bufferedinputstream (zipfile.getinputstream(entry));             int count;             byte data[] = new byte[buffer];             fileoutputstream fos = new fileoutputstream(destdir);             dest = new bufferedoutputstream(fos, buffer);              while ((count = is.read(data, 0, buffer)) != -1)                {                dest.write(data, 0, count);               }               //close streams             dest.flush();             dest.close();             is.close();           }           }       catch(exception e)            {           e.printstacktrace();          throw new exception();           }      }

you trying write directory

fileoutputstream fos = new fileoutputstream(destdir);

try changing

fileoutputstream fos = new fileoutputstream(destdir + file.separator + entry.getname ());

using zipfile entry 's name
