Answer Posted / mohammad faisal
In java when we declares a variable, at runtime it
initialize and allocated a memory space.
Change in the value of variable result in the change of
output.
Now,
In pass by value,
when a value is passed, the function creates its own
variable and assign it the passed value.
So any change made by that function will not change the
value of actual variable which is passed.
In pass by refernce,
instead of passing the value we pass the address of the
variable. In this case, the function does not allocate any
memory to its variable but the variable just point to the
passed variable. Any change made by the function result in
change the value of actual variable.
