The stack iterator causes some slight overhead for checking whether the stack has been modified, whereas iteration over the array would be fast.

<p>I am trying to fetch an RTSP stream over HTTP using a proxy. The behavior of the Real client seems to be a bit hectic: it tries all the possible ports, methods and protocols at once. The only thing that should work is HTTP GET over port 80. Such a request is indeed issued, and is received on the server. Here's how t... | <p>First, you might want to read this:</p>

<p>I've just completed a Silverlight project and it's time to have a little clean up. I'd like to take my core files and put them into a separate project which I will reference from my main Silverlight app.

<p>Is it possible, in Java, to enforce that a class have a specific set of subclasses and no others? For example:</p>

public final class B extends A {}
public final class C extends A {}
public final class D extends A {}
</code></pre>
<p>Can I somehow enforce that no other subclas... | <p>Give class <strong><code>A</code></strong> a constructor with package-level accessibility (and no other constructors).</p>
<p><sup>Thanks, Dave L., for the bit about no other constructors.</sup></p>
| <p>You could put class A,B,C,D in a seperate package and make class A not public.</p>
