Чтение разорванного файла в 2d массив - печать - и поиск среднего числа столбцов

Question

У меня проблемы с чтением всего файла и помещением его в массив. Это продолжает пропускать последние 2 числа в моем текстовом файле. Что я делаю неправильно в моем методе createArr(), который вызывает это. Кроме того, мой метод avgTimeTemp() не производит никакого вывода, кроме первой строки. Я включил содержимое моего текстового файла ниже и вывод.

Содержание текстового файла

98 95 95 102

99 96

99,5 97

100 97,5 97,5

101 98,5 98 101 100 102,5

99,5

99,5 95 96,5 102 97,5
