So, can i say that for 2^32 different strings, the hashcode function will always produce different hashcode?

@Zara Actually it even says quite the opposite! Having 2^32 different strings you will most likely have a collision (or even several..).

@jory - yes you are right. It's an example of the birthday paradox. (It is not entirely impossible that 2^32 different randomly generated strings will all have different hashcodes. Just vanishingly improbable.)
