java - why does the toString method shows error? -


this code. have overridden tostring() method. so, when object e being printed overridden method must called. don't see method being called. 

public static void main(string[] args) {          try         {             string name="foo";             int =integer.parseint(name);         }catch (numberformatexception e)         {             system.out.println(e);         }      }     public string tostring()     {         return "err";     }  }

you have overridden tostring on whatever class have made. writing system.out.println(e); implicitly invoke tostring method on numberformatexception class, not on class.

why attempting override tostring on numberformatexception, anyway? what's wrong system.out.println(e.getmessage()); or e.printstacktrace();?

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
