wants us to do a magic box, that is, it wants to create a matrix of size 3 * 3 matrix, the data collected as a line, summed up in the colon, cross will be the same as the aggregated totals. Example, the hand that add up as we saw below Collect what you'll find the value of 15. 3 * 3 the size of the user is not getting us to create a data matrix and wants us to check if you have magic. Below that wants to be written into the program using methods of
. Programma che
QuadratoMagico
e delle Colonna di ogni Identica diagonal. Esempio di quadrato
2 9 4 6 1 8 7 5 3
E 'possibile definire a class for this purpose and likely QuadratoMagico
has the following methods and constructors: public
QuadratoMagico (int s) that creates a magic square of size sx s.
public void fill (): filling the array of numbers of QuadratoMagico with values \u200b\u200btaken from the keyboard.
public void print (): print to video to the array of numbers contained in the type QuadratoMagico.
public boolean check () which returns true if the array is a magic square, false otherwise.
write a simple main ():
a) creates an object type of magic square of size 3x3;
b) requires input from keys of the array elements;
c) check whether the square and the 'magic or not;
d) printing the result of computation.
sample run:
Inserting the values \u200b\u200bof the square of size 3
1 2 3 4 5 6 7 8 9
The square:
1 2 3 4 5 6 7 8
9
