I am doing a simple task. I am assigning strings, ints, and a double to variables. The variables are being assigned through a scanner reading a text file. The scanner cannot read the double. It throws a input mismatch exception. I have researched stack overflow for the answer and I have tried the following solutions:
- Scanner double value - InputMismatchException
- Scanner InputMismatchException from file
- How to read double in java from a file
- Reading from file double value using Scanner - InputMismatchException?
The text file reads as follows:
Pebbles Flinstone\n
1 2.2\n
This is a line of text\n
This is my code:
public static void main(String[] args) throws FileNotFoundException {
File file = new File("input.txt");
Scanner scanner = new Scanner(file);
String s1 = scanner.next(); // s1 is assigned to Pebbles
String s2 = scanner.next(); // s2 is assigned to Flintstone
int x = scanner.nextInt(); // x is assigned to 1
double y = scanner.nextDouble(); // y is assigned to 2.2
scanner.nextLine(); // Advance scanner to beginning of next line
String s3 = scanner.nextLine();
scanner.close(); // s3 is assigned to "This is a line of text"
System.out.print(y);
}
How do I get the scanner to read 2.2 as a double? Changing the Locale doesn't work. Changing the decimal to a comma does not work either.
