Method Details

parseUnsignedInt

public static int parseUnsignedInt(@Nullable
 String s,
 int radix)
                            throws NumberFormatException

Counterpart of Integer.parseInt(String, int) for parsing unsigned integers.

Redundant with java.lang.Integer.parseUnsignedInt(String, int radix), which is available since Java 8.

Returns:

0 through 2³² - 1

Throws:

NumberFormatException - s is null or empty

NumberFormatException - radix is out of range (see Character.digit(char, int))

NumberFormatException - The value represented by s is larger than 2³² - 1

NumberFormatException - s contains characters that are not valid digits for the given radix (see Character.digit(char, int))

parseUnsignedLong

public static long parseUnsignedLong(@Nullable
 String s,
 int radix)
                              throws NumberFormatException

Counterpart of Long.parseLong(String, int) for parsing unsigned integers.

Redundant with java.lang.Long.parseUnsignedLong(String, int radix), which is available since Java 8.

Returns:

0 through 2⁶⁴ - 1

Throws:

NumberFormatException - s is null or empty

NumberFormatException - radix is out of range (see Character.digit(char, int))

NumberFormatException - The value represented by s is larger than 2⁶⁴ - 1

NumberFormatException - s contains characters that are not valid digits for the given radix (see Character.digit(char, int))
