Я хочу сделать викторину с вопросами и уникальным изображением для каждого вопроса.Например,
Не знаю почему, но в окнах с вопросами нет изображений.Например, в окне с вопросом «Какая столица Нидерландов?» Отсутствует изображение «information.jpg» из файла «Quiz.java». Как я могу поместить изображения в окнах с вопросами, поставить уникальное изображение для каждого вопроса?Пожалуйста, помогите
Когда я выбрал папку с изображениями book.jpg, science.jpg, wisdom.jpg: C: \ Users \ syuye \ eclipse-workspace \ test \ src \ test,появилось сообщение об ошибке
Поэтому я сохранил файл как utf-8.Может, это как-то повлияло?
на c0der: Да, я добавил e.printStackTrace (); :
JLabel picLabel = new JLabel(new ImageIcon(myPicture));
img.add(picLabel);
add(img);
} catch (Exception e) {e.printStackTrace();}
