java - Cannot retrieve a Float array from a hashtable -


i limited using legacy collections in java. created hashtable

private hashtable datastock = new hashtable();

and 1 of entries of hashtable float array

datastock.put("somearray", new float[24]);

when want retrieve entry hashtable this:

float[] anotherarray = (float[]) datastock.get("somearray");

i following cast exception:

exception in thread "main" java.lang.classcastexception @ java.lang.throwable.fillinstacktrace(<unknown source file>:130) @ java.lang.throwable.<init>(<unknown source file>:51) @ java.lang.exception.<init>(<unknown source file>:13) @ java.lang.runtimeexception.<init>(<unknown source file>:18) @ java.lang.classcastexception.<init>(<unknown source file>:17) @ fr.ecosense.business.flashmemory.restorestockdata(flashmemory.java:297)

what doing wrong? why storing arrays in hashtable different storing other objects? looking explication there little information on storing arrays in hashtables.

edit: using java me. maybe can cause unexpected behaviour..

just demonstration. piece of code:

    hashtable datastock = new hashtable();     datastock.put("somearray", new float[24]);     float[] anotherarray = (float[]) datastock.get("somearray");

works well. means, somewhere in code put datastock other value key somearray type differs float[].

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...
