ParseLong("Hazelnut", 10) throws a NumberFormatException ParseLong("99", 8) throws a NumberFormatException The value represented by the string is not a value of type.'+' ( '\u002B') provided that the string is Radix, except that the first character may be a minus sign Any character of the string is not a digit of the specified.The radix is either smaller than Character.MIN_RADIX or larger than Character.MAX_RADIX.The first argument is null or is a string of.Thrown if any of the following situations occurs: Java programming language source code - except that eitherĪn exception of type NumberFormatException is Of the string as a type indicator, as would be permitted in ( '\u006C') is permitted to appear at the end ( '\u002B') to indicate a positive value. Indicate a negative value or an ASCII plus sign '+' String must all be digits of the specified radix (as determinedīy whether Character.digit(char, int) returnsĪ nonnegative value), except that the first character may be an Parses the string argument as a signed long in the Value represented by the argument in hexadecimal Returns: the string representation of the unsigned long Parameters: i - a long to be converted to a string. With leading zeros and for byte arrays includes for each byteĪ delimiter, prefix, and suffix. HexFormat formats and parses uppercase or lowercase hexadecimal characters, Of byte arrays and primitives to return a string or adding to an Appendable. Long.toHexString(n).toUpperCase() API Note: The HexFormat class provides formatting and parsing The String.toUpperCase() method may be called These are the characters '\u0030' through Theįollowing characters are used as hexadecimal digits: Unsigned magnitude will not be the zero character. Otherwise, the first character of the representation of the If the unsigned magnitude is zero, it is represented by a String s by calling Long.parseUnsignedLong(s, The value of the argument can be recovered from the returned This value is converted to a string ofĪSCII digits in hexadecimal (base 16) with no extra The unsigned long value is the argument plusĢ 64 if the argument is negative otherwise, it isĮqual to the argument. Returns a string representation of the longĪrgument as an unsigned integer in base 16. Returns: a string representation of the argument in the specified radix. radix - the radix to use in the string representation. Long.toString(n, 16).toUpperCase() Parameters: i - a long to be converted to a string. If uppercase letters areĭesired, the String.toUpperCase() method may The digits for hexadecimal (radix 16) areĠ123456789abcdef.
