Я хотел бы построить таблицу с использованием SQLite, которая включает в себя 4500 аэропортов по всему миру, и я не знаю, как я могу их вставить.Вставить большое количество записей
Airport.java
public class Airport {
int id;
String name, icao, iata, country, city, countryCode;
public Airport() {
}
public Airport(int id,String name,String icao,String iata, String country, String city, String countryCode)
{
this.id = id;
this.name = name;
this.icao = icao;
this.iata = iata;
this.country = country;
this.city = city;
this.countryCode = countryCode;
}
public Airport(String name,String icao,String iata, String country, String city, String countryCode)
{
this.name = name;
this.icao = icao;
this.iata = iata;
this.country = country;
this.city = city;
this.countryCode = countryCode;
}
public String getName() {
return this.name;
}
public String getICAO()
{
return this.icao;
}
public String getIATA()
{
return this.iata;
}
public String getCountry()
{
return this.country;
}
public String getCity()
{
return this.city;
}
public String getCountryCode()
{
return this.countryCode;
}
}

ErrorLog: Ошибка: (18, 20) ошибка: код слишком большой
Проблема заключается в том, что слишком большой код, поэтому он не может быть скомпилирован. Как можно эффективно вставить эти записи?
* «Проблема в том, что слишком большой код, поэтому его невозможно скомпилировать ...» * - укажите точное сообщение об ошибке, с которым вы сталкиваетесь. В противном случае просто уменьшите код: (1) предварительно создайте базу данных в автономном режиме и включите ее в качестве ресурса; или (2) путем предоставления информации о аэропорте в текстовом файле в качестве ресурса и заполнения его при запуске. – jww
У меня есть текстовый файл, который включает в себя весь код строки JAVA (строки 4500 db.AddAirport()) Есть ли способ выполнить эти коды из текстового файла? – Avi
