Мобильная версияКогда я запускаю программу в IntelliJ, слишком много предупреждающих сообщений показывают в консоли (и то же самое происходит, когда программа работает в CMD) , < /p>
- Я хочу знать, как остановить эти предупреждающие сообщения, поскольку информация о шрифтах и любых других может быть проигнорирована. Значение PDF417 - это одно из этой программы. >
