intbytesToInt(final byte[] arr)
Returns an int extracted from a Little-Endian byte array. 
int v = 0;

intbytesToInt(final byte[] bytes, final int position, final int length, final int bitShiftStart, final int bitShitIncrement)
bytes To Int 
if (length > 4)
    throw new IllegalArgumentException("The maximum capacity for an int is 32 bytes");

intbytesToInt(int off, byte... arr)
bytes To Int 
int n = 0;

    n |= (arr[i + off] & 0xFF) << 8 * i;
return n;
intbytesToInt16(byte highByte, byte lowByte)
Converts 2 bytes to a signed integer sample with 16bit range. 
return (highByte << 8) | (lowByte & 0xFF);
intbytesToInt2(byte[] arr, int offset)
bytes To Int 
int value;
value = (int) (((arr[offset] & 0xFF) << 24) | ((arr[offset + 1] & 0xFF) << 16)
        | ((arr[offset + 2] & 0xFF) << 8) | (arr[offset + 3] & 0xFF));
