, когда я добавить около 60 000 объектов класса путешествия в ArrayList. Он дает ошибку java.lang.outofmemory, и я увеличил максимальный размер до 1 ГБ. Есть ли другой вариант, чем ArrayList для больших элементов.
Не могли бы вы высказать, как вы его загрузили? – vincent
«ArrayList» вряд ли будет вашей проблемой. Хотя, правильное определение «ArrayList» при создании было бы полезным. –
Я прочитал xml-файл, затем добавлю элемент в arraylist. приватный список lstJourney = new ArrayList (); public void endElement (String uri, String localName, String qName) throws SAXException { \t \t // logger.info ("END element" + qName); \t \t if (qName.equalsIgnoreCase ("Journey")) { \t \t \t // printJourney (путешествие); \t \t \t lstJourney.add (путешествие); } } –
