Examples of java.util.Scanner.nextDouble()

java.util.Scanner.nextDouble()
Scans the next token of the input as a double. This method will throw InputMismatchException if the next token cannot be translated into a valid double value. If the translation is successful, the scanner advances past the input that matched.
If the next token matches the Float regular expression defined above then the token is converted into a double value as if by removing all locale specific prefixes, group separators, and locale specific suffixes, then mapping non-ASCII digits into ASCII digits via {@link Character#digit Character.digit}, prepending a negative sign (-) if the locale specific negative prefixes and suffixes were present, and passing the resulting string to {@link Double#parseDouble Double.parseDouble}. If the token matches the localized NaN or infinity strings, then either "Nan" or "Infinity" is passed to {@link Double#parseDouble(String) Double.parseDouble} as appropriate. @return the double scanned from the input @throws InputMismatchException if the next token does not match the Float regular expression, or is out of range @throws NoSuchElementException if the input is exhausted @throws IllegalStateException if this scanner is closed
