Упрощение итеративного логического цикла, оценка легального шахматного хода в идиоматической Java

Question

Позвольте мне сначала заявить, что я хорошо знаю, что то, что вы собираетесь увидеть, шокирует и беспокоит, однако, оно работает, и поэтому я его использую, но мне действительно нужно его почистить.Дело в том, что я пока не смог его зафиксировать.

Вот оно:

    for (int i = 0; i < 8; i++) {
        for (int j = 0; j < 8; j++) {

Это проверяет, что пространство, в которое вы собираетесь двигаться, какКороль в шахматах, не находится под угрозой от королевы или епископа.

Как я могу сделать это с помощью цикла?Это помогло бы мне обобщить это на случай, когда мы не просто проверяем направление положительной разности обеих координат.
