About Question enthuware.ocajp.i.v7.2.1252 :

[joao.pedro.ferreira]

This question is related with type immutable ? char is immutable and char[] is mutable?
I don't understand why char c don't change the value and char[ ] cA change.

No, it is not related to mutability. It is related to pass by value/pass by reference. This discussion might be helpful for you: http://stackoverflow.com/questions/4048 ... -reference

Just something I've noticed. The println has value1 + ", " (with a space) + value2, but all answers have value1 + "," (without a space) + value2. So none of the answers would be correct.

You are right. Fixed.
