decodeHex

public static byte[] decodeHex(String data)

decodeHex

public static byte[] decodeHex(char[] data)
                        throws CodecException

Converts an array of characters representing hexadecimal values into an array of bytes of those same values. The returned array will be half the length of the passed array, as it takes two characters to represent any given byte. An exception is thrown if the passed char array has an odd number of elements.

参数:

data - An array of characters containing hexadecimal digits

返回:

A byte array containing binary data decoded from the supplied char array.

抛出:

CodecException - Thrown if an odd number or illegal of characters is supplied

3.4.1

encodeHex

public static char[] encodeHex(byte[] data)

Converts an array of bytes into an array of characters representing the hexadecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

参数:

data - a byte[] to convert to Hex characters

返回:

A char[] containing hexadecimal characters

encodeHex

public static char[] encodeHex(byte[] data,
                               boolean toLowerCase)

Converts an array of bytes into an array of characters representing the hexadecimal values of each byte in order. The returned array will be double the length of the passed array, as it takes two characters to represent any given byte.

参数:

data - a byte[] to convert to Hex characters

toLowerCase - true converts to lowercase, false to uppercase

返回:

A char[] containing hexadecimal characters

encodeHexString

public static String encodeHexString(byte[] data)

Converts an array of bytes into a String representing the hexadecimal values of each byte in order. The returned String will be double the length of the passed array, as it takes two characters to represent any given byte.

参数:

data - a byte[] to convert to Hex characters

返回:

A String containing hexadecimal characters

从以下版本开始:

1.4

encodeHexString

public static String encodeHexString(byte[] data,
                                     boolean lowerCase)

参数:
