TASK 2 (50%)
Research and write a report detailing the importance to software development of high
cohesion, loose coupling, data hiding and information hiding (1500 words).
Write the Java code for the following exercises and provide appropriate unit tests using
JUnit. All code must be submitted to the repository mentioned in Task 1, with evidence of
continuous commits.
Build a Connect 4 style Console game which allows the players to select the column they
wish to drop their counter (O or X) down. The program should be able to detect a winning
horizontal, vertical or diagonal line of 4 matching counters, then stop the game and declare
the winner. However, in our version of the game, we will allow each player two optional
special moves that they can each play once during the game. These are:
1. BLITZ activated by pressing the B key and selecting a column to clear.
2. TIME BOMB activated by pressing the T key and selecting a column. This places a special
symbol ‘*’ in the selected column as normal. However, it clears the counters surrounding it
horizontally, vertically and diagonally after the next player has made 2 more moves.
The game might look like this:
0 1 2 3 4 5 Player 1 X
- - - - - - Player 2 O
- - - - - -
X - - - - -
