user interface - Java- random spawning of rectangles -


here's part of code doesn't work want.when rectangle in loop painted, it's every time painted @ same place, despite fact used random number x , y axis.i paint rectangle 5 times (as it's set in loop) , each on random coords.if whole code necessary, let me know please.thank you!

    public void paintcomponent(graphics g){     random=new random();     rx=random.nextint(500);     ry=random.nextint(500);     super.paintcomponent(g);              for(int i=0;i<=5;i++){         g.fillrect(rx,ry,20,20);         }       g.setcolor(color.red);     g.filloval(x,y,20,20);  }

currently code generates coordinates 1 time. (thanks jon skeet pointing out)

if want paint 5 different trianlges should move call random.nextint inside loop.

public void paintcomponent(graphics g){     random=new random();      super.paintcomponent(g);          for(int i=0; i<=4; i++){         rx=random.nextint(500);         ry=random.nextint(500);         g.fillrect(rx,ry,20,20);     }       g.setcolor(color.red);     g.filloval(x,y,20,20);  }

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...
