Defining a constant in Java - 


        public enum categories {         general, lights, effects, interactive, ui("ui"), optimizations, parsers, animation, materials, about;          private string name;          categories() {             name = tostring().tolowercase(locale.getdefault());             name = name.substring(0, 1).touppercase(locale.getdefault()) + name.substring(1, name.length());         }          categories(string name) {             this.name = name;         }          public string getname() {             return name;         }      }

inside enumeration first line starting "general, effects" wondering are? ui("ui"). meant constants? why ui("ui") have ( , ) when rest of them don't?

thanks in advance...

public enum categories {     general, lights, effects, interactive, ui("ui"), ...

these represent enum constants accessible qualifying them class name as

categories.general, categories.lights, categories.ui, ...

enums behave lot class except meant representing constants. so, can have constructors , fields well. while general used no-argument constructor

categories() {     name = tostring().tolowercase(locale.getdefault());     name = name.substring(0, 1).touppercase(locale.getdefault()) +            name.substring(1, name.length()); }

ui("ui") used other overloaded constructor (since passed matching string argument)

categories(string name) {     this.name = name; }

just class, enum defines member field well

private string name;

which can accessed through public getter method as

categories.ui.getname();

php - Calling a template part from a post -

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...
