这段代码最后两行有什么作用

if(cmdOk  == command)
        {
            bmkNew.title = tfTitle.getString();
            if( (bmkNew.title == null) || (0  == bmkNew.title.length()))
            {
                bmkNew.title = Config.getString(24) + (new Integer(bmkNew.position)).toString();
            }
            bookmarkListener.newBookmark(bmkNew);
        } else
        if(command != cmdCancel);
