Method

byte[]convertInt8(int v)
Convert 8-bits integer value to bytes arrays. 
byte[] bytes = new byte[1];
bytes[0] = (byte) v;
return bytes;
Integer[]convertIntArray(int[] arr)
convert Int Array 
Integer[] ret = new Integer[arr.length];
for (int i = 0; i < arr.length; i++) {
    ret[i] = arr[i];
return ret;
byte[]convertIntArray(int[] in)
This function converts an array of type int into an array of type byte 
byte[] out = new byte[in.length];
for (int i = 0; i < in.length; i++) {
    out[i] = (byte) in[i];
return out;
intconvertIntArrayFromHex(char[] hex)
convert Int Array From Hex 
int hexLen = hex.length;
if (hexLen < 8)
    throw new IllegalArgumentException("Too few characters: " + hexLen);
return (getHex(hex[0]) << 28) | (getHex(hex[1]) << 24) | (getHex(hex[2]) << 20) | (getHex(hex[3]) << 16)
        | (getHex(hex[4]) << 12) | (getHex(hex[5]) << 8) | (getHex(hex[6]) << 4) | (getHex(hex[7]));
intconvertIntBitsMSBinaryToIEEE(int source)
Converts a Microsoft Binary Float integer bits into a IEEE equivalent Assume all the bits are arrange in a the big endian format 
int mantissa = source & 0x007FFFFF;
int sign = (source & 0x00800000) >> 23;
int exponent = (source & 0xFF000000) >>> 24;
exponent = exponent - 0x81 + 0x7F; 
sign = sign << 31;
exponent = exponent << 23;
int retVal = mantissa | sign | exponent;
return retVal;

byte[]convertIntColourToByteArray(int intColour)
convert Int Colour To Byte Array 
byte[] colourByteArray = new byte[3];
colourByteArray[0] = (byte) (intColour >> 16 & 255);
colourByteArray[1] = (byte) (intColour >> 8 & 255);
colourByteArray[2] = (byte) (intColour & 255);
return colourByteArray;
double[][]convertIntDouble(int[][] in)
Convert an integer 2-D array to a double array. 
double[][] ret = new double[in.length][in[0].length];
for (int i = 0; i < in.length; i++) {
    for (int j = 0; j < in.length; j++)
        ret[i][j] = (double) in[i][j];
return ret;
StringconvertInteger(String input, int maxLen)
convert Integer 
int output = 0;
int idx = maxLen;
if (input.length() < maxLen) {
    idx = input.length();
try {
    output = Integer.parseInt(input.substring(0, idx));
} catch (Exception e) {
...
IntegerconvertInteger(String str)
convert Integer 
int val = 0;
try {
    val = Integer.parseInt(str);
} catch (NumberFormatException ex) {
return new Integer(val);
int[]convertIntegerArrayToInt(Integer[] integerArray)
convert Integer Array To Int 
int[] intArray = new int[integerArray.length];
for (int i = 0; i < integerArray.length; i++) {
    intArray[i] = integerArray[i];
return intArray;
