Outlab 6: Battleship
Due: Monday 8 Aug at 10 pm
Apply everything you have learned this semester to solve a
moderately sized problem (with many little sub-problems) with
minimal guidance. i.e. Show me how well you can think for
This is a lab that allows you to work with 1 partner. A group of two is the maximum.
You will build an application that allows a person to play Battleship
against the computer. I will provide you a Driver and a class to
represent spots on the board. You must use what I provide and
build your own class to represent the game.
Your application will create the board, place ships randomly, ask
the user for spots they want to shoot at, report/update the
result, and repeat until the game is over (all ships are hit in
each spot they occupy). You must also be able to report the number
of guesses it took the user to finish the game.
There will also be limited error checking as described below.
- Create an Outlab6 project and type this
into a Driver, and this into a class
called Spot. Neither of these will be changed.
- Read through the Driver and understand the flow of how this
program will execute.
- Here are some specifications and assumptions for you:
- The board size can change in the Constructor call. Just
because the current Driver makes a 5x7 board does not give you
permission to assume it will always be that size. You can
assume the board will always be big enough to put the ships in
randomly (5x4 or 4x5).
- The numbering of rows and columns in the printed output must
start at 1, not 0. The user will use those values to reference
spots in the board. (see output)
- There are 4 ships that need to be placed on the board. The
Carrier occupies 5 spots, the Battleship 4, Submarine 3, and
Patrol Boat 2.
- The ships will be placed randomly (random location, random
vertical/horizontal orientation). This ships will not be
placed diagonally and must not overlap.
- The output style and user interaction must match the sample
- The following errors must be caught: sample
Here is sample output.
- The user cannot input a row or column value that does not
- The user cannot chose a spot that they already selected.
- The user cannot input anything other than an int for row
and column values (we'll talk about this on 19 November).
- Good Luck! Use what we have learned this semester about
design. Work one method at a time. Test test test.
By Monday 8 August at 10:00 pm, submit the file Battleship.java
into the appropriate D2L dropbox folder. DO NOT SUBMIT
Grading - 20 points
- 2 points - The Constructor is simple and does not save the
input parameters as instance variables.
- 2 points - The print method produces output formatted in the
same way as the sample output correctly uses the boolean
- 5 points - The ships are all placed randomly (and not
overlapping) and will be placed successfully every single time
in a board of size (5x4 or 4x5).
- 4 points - The makeGuess() method works as the output
suggests, to include handling the errors described above.
- 2 points - The over() and printStatistics() methods work and
are very simple.
- 5 points - Good programming principles are followed (comments,
minimal unnecessary code, appropriate delegation of
