[<Android.Runtime.Register("nextInt", "()I", "")>]
member this.NextInt : unit -> int

Returns

the int scanned from the input

if this Scanner has been closed.

if input has been exhausted.

if the next token can not be translated into a valid int value.

Remarks

NextInt(Int32)

Scans the next token of the input as an int.

[Android.Runtime.Register("nextInt", "(I)I", "")]
public int NextInt (int radix);
[<Android.Runtime.Register("nextInt", "(I)I", "")>]
member this.NextInt : int -> int

Parameters

radix
Int32

the radix used to interpret the token as an int value

Returns

the int scanned from the input

Attributes

Exceptions

if this Scanner has been closed.

if input has been exhausted.

if the next token can not be translated into a valid int value.

Remarks

Scans the next token of the input as an int. This method will throw InputMismatchException if the next token cannot be translated into a valid int value as described below. If the translation is successful, the scanner advances past the input that matched.

If the next token matches the <i>Integer</i> regular expression defined above then the token is converted into an int value as if by removing all locale specific prefixes, group separators, and locale specific suffixes, then mapping non-ASCII digits into ASCII digits via Character#digit Character.digit, prepending a negative sign (-) if the locale specific negative prefixes and suffixes were present, and passing the resulting string to Integer#parseInt(String, int) Integer.parseInt with the specified radix.

If the radix is less than Character#MIN_RADIX Character.MIN_RADIX or greater than Character#MAX_RADIX Character.MAX_RADIX, then an IllegalArgumentException is thrown.
