For
example:
|
|
|
int
my_func(String s) {
|
|
|
return
s.length();
|
|
|
}
|
|
|
– |
The
length method returns the number of characters in the
|
|
|
string
|
|
|
– |
s is
actually a reference to the calling routine’s string object
|
|
– |
void
is available in Java as it is in C++ to return nothing
|
|
|
from
the function
|
|
|
|
– |
While
object references are placed on the stack when a
|
|
|
function
is called – the objects to which they refer are not
|
|
|
(never).
There is no support of a “pass by value” concept
|
|
|
with
objects of a class.
|
|
|
– |
Therefore,
we will never perform a deep copy as part of a
|
|
|
function
call
