Method Detail

bytesToHex

public static String bytesToHex(byte[] bytes)

Converts a byte array into a hexadecimal string with default settings (lowercase, no spacing).

Parameters:

bytes - The byte array to convert

Returns:

A lowercase hex string without spacing

bytesToHex

public static String bytesToHex(byte[] bytes,
                                boolean lowerCase)

Converts a byte array into a hexadecimal string.

Parameters:

bytes - The byte array to convert

lowerCase - Whether the hex characters should be lowercase

Returns:

A hex string with default spacing (empty)

bytesToHex

public static String bytesToHex(byte[] bytes,
                                boolean lowerCase,
                                String spacing)

Converts a byte array into a hexadecimal string.

Parameters:

bytes - The byte array to convert

lowerCase - Whether the hex characters should be lowercase

spacing - String added between each hex value (e.g., " " for space)

Returns:

A formatted hex string with specified case and spacing

shortsToHex

public static String shortsToHex(int[] shorts)

Converts an array of shorts (contained in integers) into a hexadecimal string with default lowercase.g.

Parameters:

shorts - Array of short values (each stored as int)

Returns:

Lowercase hex string

shortsToHex

public static String shortsToHex(int[] shorts,
                                 boolean lowerCase)

Converts an array of shorts into a hexadecimal string. Each short is split into two bytes (least significant byte first), written to a ByteArrayOutputStream, then converted using bytesToHex with the specified case.

Parameters:

shorts - Array of short values (each stored as int)

lowerCase - Whether hex characters should be lowercase

Returns:

Hex string representation of the shorts array

longToByteString

public static String longToByteString(long value)

Converts a long integer a hexadecimal string. The long is converted little-endian (least significant byte first). Each pair of hex digits represents one byte, separated by spaces. Default output is lowercase.

Parameters:

value - Long value to convert

Returns:

Hex string representation in lowercase, bytes separated by spaces

longToByteString

public static String longToByteString(long value,
                                      boolean lowerCase)

Converts a long integer a hexadecimal string. The long is converted little-endian (least significant byte first). Each pair of hex digits represents one byte, separated by spaces. Case of hex characters can be specified.

Parameters:

value - Long value to convert

lowerCase - Whether hex characters should be lowercase

Returns:

Hex string representation, bytes separated by spaces
