The usual way to write character data to a stream, though, is to wrap the stream in a Writer, (often a PrintWriter), that does the conversion for you when you call its write(String) (or print(Str...

Is it possible for a computer to “learn” a regular expression by user-provided examples?
...lized into a regular expression. The only way for the computer to build a predictable regular expression is to require you to list all possible matches. Then it could generate a search pattern that matches exactly those matches.
If you don't want to list all possible matches, you need a higher-le...

What is “Orthogonality”?
...programming languages, orthogonality may be seen as how easy is for you to predict other things about that language for what you've seen in the past.
For instance, in one language you can have:

for getting the lenght.
