Aide du programme Magic Square (Java) [fermé]

Ce sont des devoirs pour mon cours d'informatique AP traitant des tableaux 2D. Fondamentalement, ce que le programme fait, c'est entrer des valeurs dans un Carré magique (toutes les lignes, colonnes et diagonales s'additionnent pour être le même nombre) et détermine s'il s'agit d'un carré magique. Mon algorithme met continuellement false (selon la méthode isMagic ()) pour quand il vérifie si c'est magique. Je crois que j'ai des problèmes dans mes méthodes row() et column() et si quelqu'un pouvait me fournir une solution qui serait grand.
