Как я могу лучше реализовать свою числовую игру? [закрыто] ⇐ JAVA

[Anonymous]

Я написал Java-код для реализации игры с числами, в которой также задействованы уровни сложности. Пожалуйста, просмотрите этот код и предложите улучшения, которые можно внести в этот код (все, включая отступы). Как я могу улучшить качество своего кода и чего мне следует избегать при его написании?
