Мне удалось разобрать первые значения из текстового файла, из которых 18 значений метрики, и преобразовать его в желаемый формат.Как разделить вложенный текстовый файл?
текстовый файл

проблема в цикле, пока не работает, как ожидалось. сначала я использовать разделитель как Whitespace и я получить 18 метрических значений
Во-вторых, я использовал delimiterTwo как «пробельных-тильда-Whitespace» «~», чтобы получить «name2» и «» значение куб.см
while (line != null) {
String[] attributes = line.split(" "); // the file, using a Whitespace as the delimiter
Metrics valueOfMetric = createMetric(attributes);
metricsss.add(valueOfMetric); // adding metric into ArrayList
line = br.readLine();
// parse delimiter as "Whitespace-tilde-Whitespace" " ~ "
String[] delimiterTwo = line.split(" ~ ");
if (delimiterTwo.length == 2) {
String[] nameValue = delimiterTwo[1].split(": ");
if (nameValue.length == 2) {
Metrics valueOfMetric = createMetric(nameValue);
metricsss.add(valueOfMetric);// adding book into ArrayList
}
}
line = br.readLine();// read next line before looping
}
, но я получаю сообщение об ошибке
ошибке исключение в потоке «главный» java.lang.ArrayIndexOutOfBoundsException: 19
это код, который я написал

oh столько кода :) – Satya

Не знаете, почему вы все это делаете. Вам не нужны строки, где все числа (то есть просто строки, которые не начинаются с пробела)? – RealSkeptic
