Here is my regex so far: ([\\w]+([\\...

I can only get a keySet(). From that Set I can get an Iterator but an Iterator seems to be something different than an Enumeration. What is the best and most per...

However, I am trying to debug my thought process, so maybe someone can help me: I use compilers all the time, and the fact that I'm giving up control over machine code generation (the layout of my caches, and the flow of electrons) does not bother me. However, giving up co...
