Method Detail
-
hex
public static String hex(char ch)
Convert a char to 4 hex uppercase digits. E.g., hex('a') => "0041".
-
hex
public static String hex(String s)
Convert a string to comma-separated groups of 4 hex uppercase digits. E.g., hex('ab') => "0041,0042".
-
hex
public static String hex(StringBuffer s)
Convert a string to comma-separated groups of 4 hex uppercase digits. E.g., hex('ab') => "0041,0042".
-
hex
public static StringBuffer hex(char ch, StringBuffer output)
Convert a char to 4 hex uppercase digits. E.g., hex('a') => "0041". Append the output to the given StringBuffer.
-
hex
public static StringBuffer hex(int ch, int width, StringBuffer output)
Convert a integer to size width hex uppercase digits. E.g., hex('a', 4, str) => "0041". Append the output to the given StringBuffer. If width is too small to fit, nothing will be appended to output.
-
hex
public static String hex(int ch, int width)
Convert a integer to size width (minimum) hex uppercase digits. E.g., hex('a', 4, str) => "0041". If the integer requires more than width digits, more will be used.
-
appendNumber
public static StringBuffer appendNumber(StringBuffer result, int n)
Append a number to the given StringBuffer in the radix 10 generating at least one digit.
-
appendNumber
public static StringBuffer appendNumber(StringBuffer result, int n, int radix, int minDigits) throws IllegalArgumentException
Append a number to the given StringBuffer in the given radix. Standard digits '0'-'9' are used and letters 'A'-'Z' for radices 11 through 36.- Parameters:
result
- the digits of the number are appended heren
- the number to be converted to digits; may be negative. If negative, a '-' is prepended to the digits.radix
- a radix from 2 to 36 inclusive.minDigits
- the minimum number of digits, not including any '-', to produce. Values less than 2 have no effect. One digit is always emitted regardless of this parameter.- Returns:
- a reference to result
- Throws:
IllegalArgumentException
-
hex
public static String hex(long i, int places)
Supplies a zero-padded hex representation of an integer (without 0x)
-
hex
