[Sharing] Checking if a given remote directroy exists

Question

I have got TWO ways to solve this:
First:

public boolean directoryexist(String remoteDirectory) throws Exception{
    if(remoteDirectory == null || remoteDirectory.equals("")){
   return false;
    }
    else{
   //list the root path
   FTPFile[] currentdirectory = this.directoryList("..");
   //Split the given remoteDirectory with "/"
   String[] targetdirectory = remoteDirectory.replace('\\', '/').split("/");
   boolean findit = false;
   for(int i=0; i< targetdirectory.length;i++){
       findit = false;
       if(targetdirectory[i].equals("..") || targetdirectory[i].equals("")){
      continue;
       }else{
      for(int j = 0; j< currentdirectory.length; j++){
          //find one path
          if(currentdirectory[j].isDir() && currentdirectory[j].getName().equals(targetdirectory[i])){
         //change into it
         this.changeDirectory(targetdirectory[i]);
         //list targetdirectory[i]
         currentdirectory = this.directoryList();   
         findit = true;
         break;
          }
      }
       }
   }
   return findit;
}

Second:

public boolean directoryExist(String remoteDirectory) throws Exception{
   boolean ifexist = true;
   if(remoteDirectory == null || remoteDirectory.equals("")){
      return false;
   }else{
      String directory = remoteDirectory.replace('\\', '/');
      try{
         this.changeDirectory(directory);
      }catch(FTPException e){
         ifexist = false;
      }
   }
   return ifexist;
}

I hope it will be helpful !!
