どんな助けでも大歓迎です...
これまでの私のコード...（おそらくとにかく必要になるでしょう...）
主要：
public class LotDriver
{
public static ParkingLot lot1;
public static void main(String[] args) throws IOException
{
System.out.println("Adam Klein's Parking Lot Revenue Checker - Previously Don Smith's");
File file1 = new File("arrivals.txt");
File file2 = new File("pickups.txt");
lot1 = new ParkingLot(101, 50);
lot1.readArrivals("arrivals.txt");
System.out.println("Total Cars parked: " + lot1.getTotalCars());
lot1.readPickups("pickups.txt");
lot1.merge(file1, file2);
lot1.outputCars();
System.out.println("Total Cars remaining: " + lot1.getTotalCars());
System.out.printf("\nTotal Revenue: %10.2f\n",lot1.getRevenue());
}
}`
別のファイルで...私はこのマージ方法を持っています
public static void merge(File file1, File file2) throws IOException {
Scanner scanner1 = new Scanner(file1);
Scanner scanner2 = new Scanner(file2);
while (scanner1.hasNextLine() && scanner2.hasNextLine())
{
String trash = scanner1.nextLine();
String trash2 = scanner2.nextLine();
String line1 = scanner1.nextLine();
String line2 = scanner2.nextLine();
// parse line1
String[] line1Tokens = line1.split(",");
// parse line2
String[] line2Tokens = line2.split(",");
// Print
String ticket = line1Tokens[0];
String arrived1 = line1Tokens[2];
String arrived2 = line1Tokens[3];
String pickup1 = line2Tokens[1];
String pickup2 = line2Tokens[2];
System.out.println("Ticket: " + ticket + ", " +
"Arrived: " + arrived1 + ":" + arrived2 + " --- " +
"Pickup: " + pickup1 + ":" + pickup2 + " --- " +
"Cost: ");
}
}
エラーがスローされます：
