Examples of java.util.Scanner.nextInt()

java.util.Scanner.nextInt()
Scans the next token of the input as an int.
An invocation of this method of the form nextInt() behaves in exactly the same way as the invocation nextInt(radix), where radix is the default radix of this scanner. @return the int 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
