Is it possible to read from a InputStream with a timeout?
...the data - that's correct behaviour; there are no available data at that point. As soon as the data are available from the shell, the method returns a value > 0. NB: Cygwin uses cmd.exe too.
Simplest solution (no blocking, so no timeout required)
Just use this:
byte[] inputData = new byt...

How does the Comma Operator work
..."or", "not", "xor";

(((keywords = "and"), "or"), "not"), "xor";
That is, the first operator called is keywords.operator =("and") which returns a proxy object on which the remaining operator,s are invoked:

What really happens in a try { return x; } finally { x = null; } statement?
...entially stores it in a variable and returns afterwards
i.e. similar to:
int tmp;
try {

try {
return SomeNumber();

Why do == comparisons with Integer.valueOf(String) give different results for 127 and 128?
...
