Where is it specified that Java is call by value?
I know that Java is by default call-by-value but I am not sure where in the Java Language Specification this is addressed. Google searching only seems to find me unofficial sources but never points to where the actual part of the specification that describes this is.
What argument passing mechanism does python use, and where is this officially documented?
As far as I am aware, python is generally referred to as ‘call-by-sharing’, but does it implement this with call-by-value (like Java) or call-by-reference? or something else? I would appreciate if this could be answered with official python documentation (in which I can’t seem to find the answer) as opposed to anything subjective.
