Indicate datatype from a input string?
<p>For example i have a string input "int",can i declare a variable base on that input?
(Not switch check please). I mean something like this (pseudo-code) or similar:<br /></p>

<pre><code> String str="int"; 
 new (variable_name,"int");
</code></pre>

<p>// create new variable with int datatype.</p>
