CHAPTER 48 — Arrays as Parameters
The last two chapters were about arrays.
The example programs used a
main() method which contained the
arrays and did all the computing.
This is not the way programs are usually written.
Usually,
arrays (and other forms of data)
are manipulated
by passing them as
parameters
to methods.
Each method is like a "tool" that does
something with an array.
For example, there may be a method
that finds the maximum element of an array,
or a method that adds up all the elements in an array.
Chapter Topics:
- Parameters of methods (review)
- Arrays as parameters
- Picture of array parameter passing
- Primitive types as parameters
