Set All to Zero
Problem Specification
In this assignment, you are required to implement a board game.The game board is a 2D matrix of integer loaded from file.The goal of the game is to set all the integers in the matrix to zero by applying different items to the game board, different items have different properties and cost step count.There is no limit in steps taken, but if the item set any value in the matrix to negative number, the game will over.
Game Flow
A game file is required to specify in the command line to start the game, following is an example:
java Game game01.txt
The file described the height, width, content and target step of the game, following is an example:
game01.txt
5
5
1 1 1 1 0
1 0 0 1 0
1 0 2 4 2
1 1 4 1 2
0 0 2 2 2
4
remark
height of the matrix
width of the matrix
line 0 of the matrix
line 1 of the matrix
line 2 of the matrix
line 3 of the matrix
line 4 of the matrix
target step
After the game is initialized, it starts to ask user to apply different items to the game board.Item can be described by a 2D matrix of integer, the default setting of an Item will print the number stored on screen, except 0 will be replaced by a space.For example,
data stored in item
1 1 1 1
1 0 0 1
1 0 0 1
1 1 1 1
the way to display item
1 1 1 1
1 1
1 1
1 1 1 1
but it can be overridden according to the needs of different item type will be explained in detail later.There are two types of item, they are Bomb and SuperBomb,
Bomb shared the same display property of Item, it costs 1 step to apply Bomb on game board.When a Bomb is applied to the game board, the value in the game board will be reduced by the corresponding value in the Bomb.For example,
Ifis applied to 2,1 of the game board
1 1 12 2 2 2 2
1 2 12 2 2 2 2
1 1 12 2 2 2 2
2 2 2 2 2
2 2 2 2 2
i.e. row is 2 and col is 1, the game board will become
2 2 2 2 2
2 2 2 2 2
2 1 1 1 2
2 1 0 1 2
2 1 1 1 2
SuperBomb behave differently, it costs 2 steps to apply SuperBomb on game board.When a SuperBomb is applied to the game board, the value in the game board will be divided by the corresponding value in the SuperBomb.For example,
Ifis applied to 2,1 of the game board
2 2 23 2 3 4 3
2 1 23 2 3 4 3
2 2 23 1 2 3 3
3 3 4 4 3
3 5 6 7 3
i.e. row is 2 and col is 1, the game board will become
3 2 3 4 3
3 2 3 4 3
3 0 1 1 3
3 1 4 2 3
3 2 3 3 3
In this version, SuperBomb only stored 2 values, either 2 or 1.The display property of SuperBomb is different from the Items default.2 will be displayed asand 1 will be displayed as space.For example, the SuperBomb above will be displayed as follow:
data stored in item
2 2 2
2 1 2
2 2 2
the way to display item
Player is asked to apply an item to the game board repeatedly until the player win the game or the game is over. Player wins the game when all the values in the game board are zero and the game is over when there is a negative number in the game board.
There are two conditions when player wins:
Condition 1:Step counttarget step count
Condition 2:Step counttarget step count
For Condition 1, it displays Congratulation, well done! and the game will be ended.For Condition 2, it displays Congratulation, you have finished the game… but you can do even better! and player will be asked if heshe want to play again.
When the game is over player lose, it displays Game Over! and also the game board.Note that, negative value will be replaced as X and player will be asked if heshe want to play again too.
If the player choose to play again, the game including the step count will be reset and start again.Otherwise the game will be ended.Note that, Bye Bye! will be printed when the game ends.
To simplify the game, the item list is fixed in this version, there are 6 Bombs and 3 SuperBombs, their matrix and id are stated as follow:
Items
012345678
1 1 1 11 1 11 111 11
1 11 111 2 11 1
1 11 1 11 11
1 1 1 1
Player can use the items as many time as they wanted.
Following are some sample output without error and exception handling.

Error checking and Exception Handling
Try to implement your program as robust as possible by considering errors that may occurs in different input.For example:
game01.txt
5
5
1 1 1 1 0
1 0 0 1 0
1 0 2 4 2
1 1 4 1 2
0 0 2 2 2
4
lines below are ignored
may put suggested answer here
6 2 2
1 2 2
0 0 0
Possible error
int value, range: 49
int value, range: 49
matrix:
correct size
correct range, i.e.
int value, range: 09
int value,1
when error occurs while reading file, the program may terminate with error message
During the game, you may check the range and type of different input, try your best to prevent exceptions like ArrayIndexOutOfBoundsException display to player, as they may not know what it is.You may display meaningful error message to player and ask again until correct answer is input.
Documentation
The documentation should include the following:
Evidence of Testing output capture of all the features that you have implemented, remember to provide few lines of description of each capture
Explanation of where your program used the concept of polymorphism

Implementation Guidelines
You are required to use ObjectOriented Programming technique in this assignment.
You may have, but not limited to the following classes: Item, Bomb, SuperBomb, GameBoard and Game.You need to model the description to classes, attributes and methods.For example:
When playing the Game, Item is applied to the GameBoard and the cost of the Item used will be accumulated to the step count of the Game.
In the statement above, we know that Game has a step count instance variable and also play method.In order to apply Items to GameBoard, Game may store one GameBoard object and 9 items can be model by Item, besides there are also two methods of Item mentioned, but their implementation are unknown in Item yet.
