title: Why use char[] instead of String?
body: <p>In <a href="http://www.docjar.com/html/api/java/lang/Thread.java.html">Thread.java</a>, line 146, I have noticed that the author used a <code>char[]</code> instead of a <code>String</code> for the name field. Are there any performance reasons that I am not aware of? <code>getName()</code> also wraps the character in a String before returning the name. Isn't it better to just use a <code>String</code>? </p>
