Method

byte[]toByteArray(String str)
Return a byte[] array from the string's chars, ANDed to the lowest 8 bits. 
byte[] retour = new byte[str.length()];
for (int i = 0; i < str.length(); i++) {
    retour[i] = (byte) (str.charAt(i) & 0xFF);
return retour;
byte[]toByteArray(String str)
to Byte Array 
char[] chars = str.toCharArray();
byte[] bytes = new byte[chars.length];
for (int i = 0; i != bytes.length; i++) {
    bytes[i] = (byte) chars[i];
return bytes;
byte[]toByteArray(String str, String separator)
Converts a string of numbers to a byte array. 
String[] fields = str.split(separator);
byte[] tmp = new byte[fields.length];
for (int i = 0; i < tmp.length; i++)
    tmp[i] = Byte.parseByte(fields[i]);
return tmp;
byte[]toByteArray(String string)
to Byte Array 
int count = string.length() / 2;
byte[] result = new byte[count];
for (int i = 0; i < count; i++) {
    char c1 = string.charAt(i * 2);
    char c2 = string.charAt(i * 2 + 1);
    result[i] = (byte) ((unhex(c1) << 4) | unhex(c2));
return result;
...
byte[]toByteArray(String string)
Convert the passed in String to a byte array by taking the bottom 8 bits of each character it contains. 
byte[] bytes = new byte[string.length()];
char[] chars = string.toCharArray();
for (int i = 0; i != chars.length; i++) {
    bytes[i] = (byte) chars[i];
return bytes;
byte[]toByteArray(String strTransInfo)
convert string of transaction's info into byte array 
if (!strTransInfo.equals(null) || !strTransInfo.equals("")) {
    byte byteTransInfo[] = strTransInfo.getBytes();
    return byteTransInfo;
} else {
    return null;
byte[]toByteArray(String uid)
Converts a UID formatted String to a byte[]. 
if (isUID(uid)) {
    byte[] result = new byte[16];
    char[] chars = uid.toCharArray();
    int r = 0;
    for (int i = 0; i < chars.length; i++) {
        if (chars[i] == '-')
            continue;
        int h1 = Character.digit(chars[i], 16);
...
byte[]toByteArray(String value)
to Byte Array 
int i, j;
int len = value.length();
if (value == null) {
    return null;
} else if (value == "") {
    return null;
} else if ((len % 2) != 0) {
    return null;
...
byte[]toByteArray(String[] anArray)
to Byte Array 
byte[] output = new byte[anArray.length];
for (int index = 0; index < anArray.length; index++)
    output[index] = Byte.parseByte(anArray[index]);
return output;
byte[]toByteArray1D(int[][] d)
to Byte Array D 
byte[] ret = new byte[d.length * d[0].length];
int k = 0;
for (int i = 0; i < d.length; i++) {
    for (int j = 0; j < d[0].length; j++) {
        ret[k++] = (byte) d[i][j];
return ret;
