Method

byte[]toByteArray(byte b)
to Byte Array 
byte[] array = new byte[1];
array[0] = b;
return array;
byte[]toByteArray(byte byteArray)
to Byte Array 
return new byte[] { byteArray };
byte[]toByteArray(byte num)
to Byte Array 
return new byte[] { num };
byte[]toByteArray(byte value)
to Byte Array 
return new byte[] { value };
byte[]toByteArray(char c)
Converts an char to the corresponding byte[] array. 
return toByteArray(c, false);
byte[]toByteArray(char[] charArray)
A utility method to convert from chars to bytes 
if (charArray == null) {
    return null;
byte[] result = new byte[charArray.length];
for (int i = 0; i < charArray.length; i++) {
    result[i] = (byte) charArray[i];
return result;
...
byte[]toByteArray(char[] chars)
to Byte Array 
byte[] bytes = new byte[chars.length];
for (int i = 0; i != bytes.length; i++) {
    bytes[i] = (byte) chars[i];
return bytes;
byte[]toByteArray(char[] chars)
Convert the given char array into a byte array. 
byte[] result = new byte[chars.length];
for (int i = chars.length - 1; i >= 0; i--) {
    result[i] = (byte) chars[i];
return result;
byte[]toByteArray(char[] src)
to Byte Array 
byte[] arr = new byte[src.length * 2];
for (int i = 0; i < src.length; i++) {
    char chr = src[i];
    arr[i * 2] = (byte) (0xff & (chr >> 8));
    arr[i * 2 + 1] = (byte) (0xff & (chr));
return arr;
byte[]toByteArray(CharSequence hexString)
Creates a byte array from a CharSequence (String, StringBuilder, etc.) containing only valid hexidecimal formatted characters. 
if (hexString == null) {
    return null;
return toByteArray(hexString, 0, hexString.length());
