Java Reference
In-Depth Information
When designing methods within classes, always think about
delegation of
responsibility
. A class is only responsible for manipulating its own data. If Java
code manipulates data from a different class, then consider moving the code to the
other class.
The
convert
method remains unchanged. The novelty is that a
DiceCup
object is created
in the
main
method. The existence of the
DiceCup
class allows us to now create a game
with several dice cups, if needed.
6.8 Multi-Class Solution to the Battleship Game
Next, we will examine a multi-class solution to the Battleship game, which was described
in Chapter 5. We will implement a simple version of the program that supports a single
board that is controlled by the computer. Here is an excerpt from an example run of the
program (user input is in italic).
