Baseball Menu Insertion sort part

Question

Я пытаюсь использовать сортировку вставки для сортировки для среднего уровня игроков. Я получаю сообщение об ошибке «Метод get (int) в типе java.util.ArrayList не применим для аргументов (double)» в строках S.get (внешний) и S.get (внутренний - 1)

Что я делаю неправильно? Как я могу это исправить?

Answer 1

S.get() и S.set() взять переменную INT так отбрасывать внутренний к междунар.

Answer 2

Вы определили inner как double, и в Java, когда вы делаете математику с double и int (например, inner - 1), вы получите double в качестве результата. This page имеет довольно хорошее объяснение.

Тогда, когда вы говорите S.get(inner - 1), вы говорите, что используете double в качестве индекса в ArrayList. documentation for ArrayList.get говорит, что вы можете использовать только int в качестве индекса, и именно поэтому вы получаете ошибку компилятора. Вам также разрешено использовать только int в качестве индекса для set, поэтому компилятор будет жаловаться на S.set(inner, ...).

Вы можете просто бросить inner к int, но было бы гораздо лучше, чтобы объявить его как int в первую очередь, так как нет никакой причины, она должна быть double.
