Examples of java.util.Scanner.nextLong()

java.util.Scanner.nextLong()
Scans the next token of the input as a long.
An invocation of this method of the form nextLong() behaves in exactly the same way as the invocation nextLong(radix), where radix is the default radix of this scanner. @return the long scanned from the input @throws InputMismatchException if the next token does not match the Integer regular expression, or is out of range @throws NoSuchElementException if input is exhausted @throws IllegalStateException if this scanner is closed
