How can I reliably determine the type of a variable that is declared using var at design time?
...int where code insight is desired) and the lexer turns this into a special token (it's called the kibitz token). Whenever the parser meets this token (which could be anywhere) it knows that this is the signal to send back all the information it has back to the editor. It does this using a longjmp be...
Set UILabel line spacing
... it with sub-classing UILabel, basically idea is to divide label text into tokens, and then identity length of each token, create a separate label for each token and append one after another. Thats it.

Why are hexadecimal numbers prefixed with 0x?
...his is great because
an integer constant now always consists of a single token,
the parser can still tell right away it's got a constant,
the parser can immediately tell the base (0 is the same in both bases),
it's mathematically sane (00005 == 05), and
no precious special characters are needed (a...
Difference between ProcessBuilder and Runtime.exec()
...of strings or a single string. The single-string overloads of exec() will tokenise the string into an array of arguments, before passing the string array onto one of the exec() overloads that takes a string array. The ProcessBuilder constructors, on the other hand, only take a varargs array of str...

What exactly does an #if 0 … #endif block do?
...
When the preprocessor sees #if it checks whether the next token has a non-zero value. If it does, it keeps the code around for the compiler. If it doesn't, it gets rid of that code so the compiler never sees it.
If someone says #if 0 they are effectively commenting out the code s...
