В настоящее время я отображение пользователя и содержание, но я хочу, чтобы напечатать
userName(CountOfMessages UserSent)+userName(CountOfMessages UserSent)
Ex: G_LO(1)+FCHAN95(6)+WVU(1)+SWONG00(1)
Я пробовал HashMap<String, Integer>, но он не работает должным образом. Функции Java 8 также не работают. Также проверен Multiset из Гуава, но безрезультатно.
Ваш вопрос непонятен ... что такое countofmessage? –
Ys count of messahe каждый пользователь отправил ... как вы можете видеть G_Lo отправлено 1message FCHAN95 SENT 6 W_UV SENT 1 ... Я хочу посчитать как это .... –
