So, I'm looking through a java library (JScience) after someone here thoughfully pointed me towards it for getting Vectors (mathematical ones, that is) in java.
Unfortunately, I've never seen anything in my life before like:

Lets break this down:
public static
Its a public static method.
Public static > DenseVector valueOf(F...
Real.ZERO; DenseVector<Real> v = valueOf(r1, r2, r3);
In this example, the type argument F number.

Design a function f such that:
f(f(x)) == 1/x
Where x is a 32 bit float
Or how about
Given a function f, find a function g such that
f(x) == g(g(x))
See Also Interview question: f(f(n)) == -n

Well, here's the C quick hack:
extern double f(double x); double g(double x) { static int parity = 0; parity ^= 1; return (parity ? x : f(x)); }
However, this breaks down if you do:
a = g(4.0); // => a = 4.0, parity = 1 b = g(2.0); //....

Can you please show how it is entire?

I read about 'side effect' from this website :
but still not understand why f = f++ considered unsafe ?
Can somebody explain?

U should first understand how the compiler interprets ....
The article of the post incrementing operator i.e f++ is confusing, it is not considered unsafe.
Ólafur's code, it might yield f == 5 or f == 6 , depending on your compiler.

The examples are genuinely interesting.
The book is elegant, fun & practical.

A question I got on my last interview:
Design a function f , such that:
f(f(n)) == -n
Where n is a 32 bit signed integer ; you can't use complex numbers arithmetic.
If you can't design such a function for the whole range of numbers, design it for the ...

Answer Snippets (Read the full thread at stackoverflow):
f(n) = abs(n)
Because there is one more negative number than there are positive numbers for twos complement integers, f(n) = abs(n) is valid for one more case than f(n) = n > 0 ? -n : n solution....
This is true for all negative numbers.
