This is a framework you can use to implement magic squares in an OOPs environment: Class: CellCell Attributes:| Attribute | Data Type | Scope | Purpose | | row | integer | - private | the row the cell is in | | column | integer | - private | the column the cell is in | | isOccupied | boolean | - private | indicates if the cells contains a value.
set to false when created | | value | integer | - private | the integer value of the cell in the magic square |
Cell Methods:| Method | Return Type | Scope | Purpose | Cell( int r,
int c) | | + public | Constructor: sets isOccuppied to false, row to r, col to c | | isOccupied() | boolean | + public | return the current value of isOccupied | setValue(
int value) | void | + public | set the value of the cell | | getValue() | int | + public | return the current cell value |
Class: MagicSquareSquare Attributes:| Attribute | Data Type | Scope | Purpose | | mSquare | Cell [][] | - private | a 2D array to hold the magic square | | size | int | - private | the size of the magic square | | startValue | int | - private | the first number start value in the square | | step | int | - private | the amount to change each new value in the magic square |

Square Methods:| Method | Return Type | Scope | Purpose | | Square() | | + public | Constructor: set the default values | square(
int size,
int start,
int step) | void | - private | called by the constructors to create the magic square | | initsquare() | void | | used by: square()
creates mSquare full of empty cells | | setValues() | void | - private | used by: square()
sets the values in magic square | | displaySquare() | void | - private | used by: square()
will display the square neatly on the screen | nextCell(
Cell currentCell) | Cell | - private | return the next cell to be occupied
used by: setValues() | nextValue(
int x) | int | - private | returns the next value to be placed in a cell
used by: setValues() |
