What's the difference between “groups” and “captures” in .NET regular expressions?
...say about it (pages 437+):
Depending on your view, it either adds
an interesting new dimension to the
match results, or adds confusion and
bloat.
And further on:
The main difference between a Group
object and a Capture object is that
each Group object contains a
collection of C...
Why is there no Constant feature in Java?
...ures that an object is immutable when accessed through a special kind of pointer called a const-pointer When in Java, in places where I'd normally want to return a const-pointer, I instead return a reference with an interface type containing only methods that shouldn't have side effects. Unfortuna...

Yes good point, unfortunately that original maintainer has not updated the project for years, fortunately though a number of forks exist most of which fix the issues you discussed.

While the intended purpose of this class is to facilitate the creation of custom map implementation according to the javadoc, this gets the job done nicely. +1. Also, readability isn't that big of an issue in this case.

What is reflection and why is it useful?
...sn't really designed to support this unless the object conforms to a known interface, but using reflection, your code can look at the object and find out if it has a method called 'doSomething' and then call it if you want to.
So, to give you a code example of this in Java (imagine the object in qu...
What's “P=NP?”, and why is it such a famous question? [closed]
...s harder (O(e^n)).
But CS speak tells that the problem is that we cannot 'convert' a non-deterministic Turing-machine to a deterministic one, we can, however, transform non-deterministic finite automatons (like the regex parser) into deterministic ones (well, you can, but the run-time of the machin...
String comparison: InvariantCultureIgnoreCase vs OrdinalIgnoreCase? [duplicate]

the characters in the strings to

This is most appropriate when
