The list of methods to do Byte Array Create are organized into topic(s).

Method

byte[]toByteArrayBE(byte b)
to Byte Array BE 
byte[] result = new byte[1];
result[0] = b;
return result;
byte[]toByteArrayForPBE(char[] chars)
Convert the given char array into a byte array for use with PBE encryption. 
byte[] out = new byte[chars.length];
for (int i = 0; i < chars.length; i++) {
    out[i] = (byte) chars[i];
int length = out.length * 2;
byte[] ret = new byte[length + 2];
int j = 0;
for (int i = 0; i < out.length; i++) {
...
byte[]toByteArrayFromPositiveInts(int[] inInts)
to Byte Array From Positive Ints 
if (inInts == null) {
    return null;
final byte[] theBytes = new byte[inInts.length];
for (int i = 0; i < theBytes.length; i++) {
    theBytes[i] = positiveIntToByte(inInts[i]);
return theBytes;
...
byte[]toByteArrayFromString(String value, int radix)
Converts a string into a byte array. 
assert 16 == radix : "Specified string to byte array conversion not supported yet";
assert (value.length() % 2) == 0 : "Hex binary string must contain even number of characters";
byte[] ret = new byte[value.length() / 2];
for (int i = 0; i < ret.length; i++) {
    int digit1 = Character.digit(value.charAt(i * 2), radix);
    int digit2 = Character.digit(value.charAt((i * 2) + 1), radix);
    assert (digit1 != -1) && (digit2 != -1) : "String could not be converted to byte array";
    ret[i] = (byte) ((digit1 * radix) + digit2);
...
byte[]toByteArrayLE(int value)
to Byte Array LE 
byte[] bytes = new byte[4];
bytes[0] = (byte) (value);
bytes[1] = (byte) (value >>> 8);
bytes[2] = (byte) (value >>> 16);
bytes[3] = (byte) (value >>> 24);
return bytes;
byte[]toByteArrayMM(int value)
to Byte Array MM 
return new byte[] { (byte) (value >>> 24), (byte) (value >>> 16), (byte) (value >>> 8), (byte) value };
byte[]toByteArrayNoConversion(String textz)
converts the specified string to an array of bytes (useful as Sleep stores byte arrays to strings) 
byte[] data = new byte[textz.length()];
for (int y = 0; y < data.length; y++) {
    data[y] = (byte) textz.charAt(y);
return data;
byte[]toByteArrays(String s)
to Byte Arrays 
final byte[] result = new byte[s.length() / 2];
for (int i = 0; i < result.length; i++) {
    result[i] = (byte) Integer.parseInt(s.substring(i * 2, i * 2 + 2), 16);
return result;
byte[]toByteArrayShifted(int... arguments)
to Byte Array Shifted 
byte[] result = new byte[arguments.length];
for (int i = 0; i < arguments.length; i++)
    result[i] = (byte) (arguments[i] - 128);
return result;
byte[][]toByteArrayShifted2(int[][] intArray)
to Byte Array Shifted 
byte[][] result = new byte[intArray.length][];
for (int i = 0; i < intArray.length; i++) {
    result[i] = toByteArrayShifted(intArray[i]);
return result;
