Валюта Formatter не работает с System.out.format

Question

Я знаю, что я делаю что-то неправильно, я просто не знаю, что. Мне нужно, чтобы все долларовые значения были в формате американской валюты. Насколько я могу судить о проблеме с использованием System.out.format с форматированием валют. У меня нет большого опыта в java, и, вероятно, есть намного лучший способ сделать это.

Выход должен выглядеть примерно так.

Answer 1

Тип вывода currency.format() является String. Измените% d на% s.

Например, Изменить это: «С степенью HighSchool вы можете заработать% d больше, чем если бы у вас не было степени». : «С высшей степенью, вы можете заработать% s больше, чем если бы у вас не было степени».
