Method Detail

parseUnsignedInt

public static int parseUnsignedInt(@Nullable
                                   java.lang.String s,
                                   int radix)
                            throws java.lang.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:

java.lang.NumberFormatException - s is null or empty

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

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

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

parseUnsignedLong

public static long parseUnsignedLong(@Nullable
                                     java.lang.String s,
                                     int radix)
                              throws java.lang.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:

java.lang.NumberFormatException - s is null or empty

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

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

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