Parses the CharSequence argument as a signed int in the specified radix, beginning at the specified beginIndex and extending to endIndex - 1.

The method does not take steps to guard against the CharSequence being mutated while parsing.

Parameters:

s     the CharSequence containing the int representation to be parsed

beginIndex     the beginning index, inclusive.

endIndex     the ending index, exclusive.

radix     the radix to be used while parsing s.

Returns: the signed int represented by the subsequence in the specified radix.

Exceptions:

NullPointerException     if s is null.

IndexOutOfBoundsException     if beginIndex is negative, or if beginIndex is greater than endIndex or if endIndex is greater than s.length().

NumberFormatException     if the CharSequence does not contain a parsable int in the specified radix, or if radix is either smaller than java.lang.Character.MIN_RADIX or larger than java.lang.Character.MAX_RADIX.

`s`		the `CharSequence` containing the `int` representation to be parsed
`beginIndex`		the beginning index, inclusive.
`endIndex`		the ending index, exclusive.
`radix`		the radix to be used while parsing `s`.

`NullPointerException`		if `s` is null.
`IndexOutOfBoundsException`		if `beginIndex` is negative, or if `beginIndex` is greater than `endIndex` or if `endIndex` is greater than `s.length()`.
`NumberFormatException`		if the `CharSequence` does not contain a parsable `int` in the specified `radix`, or if `radix` is either smaller than `java.lang.Character.MIN_RADIX` or larger than `java.lang.Character.MAX_RADIX`.
