Indicate a negative value or an ASCII plus sign '+' Nonnegative value), except that the first character may be an Whether Character.digit(char, int) returns a Must all be digits of the specified radix (as determined by Parses the string argument as a signed integer in the radix toString public static String toString(int i).Since: JDK1.0.2 See Also: parseUnsignedInt(String, int), Represented by the argument in binary (base 2). Returns: the string representation of the unsigned integer value Parameters: i - an integer to be converted to a string. String s by calling Integer.parseUnsignedInt(s, 2).Ĭharacters '0' ( '\u0030') and '1' ( '\u0031') are used as binary digits. In binary (base 2) with no extra leading 0s. If the argument is negative otherwise it is equal to the toBinaryString public static String toBinaryString(int i).Represented by the argument in octal (base 8). String s by calling Integer.parseUnsignedInt(s, 8).įollowing characters are used as octal digits: In octal (base 8) with no extra leading 0s. toOctalString public static String toOctalString(int i).Represented by the argument in hexadecimal (base 16). Integer.toHexString(n).toUpperCase() Parameters: i - an integer to be converted to a string. 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 Integer.parseUnsignedInt(s, 16). The value of the argument can be recovered from the returned In hexadecimal (base 16) with no extra leading This value is converted to a string of ASCII digits If the argument is negative otherwise, it is equal to theĪrgument. The unsigned integer value is the argument plus 2 32 Returns a string representation of the integer argument as an toUnsignedString public static String toUnsignedString(int i,.Returns: a string representation of the argument in the specified radix. radix - the radix to use in the string representation. Integer.toString(n, 16).toUpperCase() Parameters: i - an integer to be converted to a string. If uppercase letters areĭesired, the String.toUpperCase() method may The digits for hexadecimal (radix 16) areĠ123456789abcdef. The following ASCII characters are used as digits:Īre used as radix- N digits in the order shown. The representation of the magnitude will not be the zeroĬharacter. ( '\u0030') otherwise, the first character of Represented by a single zero character '0' The remaining characters of the result represent the magnitude Negative, no sign character appears in the result. If the first argument is negative, the first element of the Or larger than Character.MAX_RADIX, then the radix If the radix is smaller than Character.MIN_RADIX The ulong type also occupies 8 bytes and can store values from 0 to 18 446 744 073 709 551 615.Returns a string representation of the first argument in the The size of the long type is 8 bytes (64 bits). It takes 4 bytes of memory and allows expressing integers from 0 to 4 294 967 295. The size of the int type is 4 bytes (32 bits). The minimum value is 0, the maximum value is 65 535. The unsigned short type is the type ushort, which also has a size of 2 bytes. The size of the short type is 2 bytes (16 bits) and, accordingly, it allows expressing the range of values equal to 2 to the power 16: 2^16 = 65 536.Since the short type is a signed one, and contains both positive and negative values, the range of values is between -32 768 and 32 767. The first letter u in the name of the uchar type is the abbreviation for unsigned. The minimum value is zero, the maximum value is 255. The uchar integer type also occupies 1 byte of memory, as well as the char type, but unlike it uchar is intended only for positive values. The char type can contain both positive and negative values. The char type takes 1 byte of memory (8 bits) and allows expressing in the binary notation 2^8=256 values.
