Method

intBytesToInt(byte[] value)
Bytes To Int 
int result = 0;
for (int i = 0; i < 4; i++) {
    int shift = (4 - 1 - i) * 8;
    result += (value[i] & 0x000000FF) << shift;
return result;
intbytesToInt(byte[] bytes)
bytes To Int 
return bytes[3] & 0xFF | (bytes[2] & 0xFF) << 8
        | (bytes[1] & 0xFF) << 16 | (bytes[0] & 0xFF) << 24;
intbytesToInt(byte[] bytes)
bytes To Int 
return bytes[3] & 0xFF | (bytes[2] & 0xFF) << 8
        | (bytes[1] & 0xFF) << 16 | (bytes[0] & 0xFF) << 24;
intbytesToInt(byte[] bytes, int offset)
bytes To Int 
int value = 0;
for (int bi = 0; bi < 4; ++bi) {
    value |= (0x000000FF & (int) bytes[bi + offset]) << (bi * 8);
return value;
intswap32bitFromArray(byte[] value, int offset)
Reads a signed 32 bit integer from an array coming from a device. 
int v = 0;
v |= ((int) value[offset]) & 0x000000FF;
v |= (((int) value[offset + 1]) & 0x000000FF) << 8;
v |= (((int) value[offset + 2]) & 0x000000FF) << 16;
v |= (((int) value[offset + 3]) & 0x000000FF) << 24;
return v;
voidswap32bitsToArray(int value, byte[] dest, int offset)
Swaps an unsigned value around, and puts the result in an array that can be sent to a device. 
dest[offset] = (byte) (value & 0x000000FF);
dest[offset + 1] = (byte) ((value & 0x0000FF00) >> 8);
dest[offset + 2] = (byte) ((value & 0x00FF0000) >> 16);
dest[offset + 3] = (byte) ((value & 0xFF000000) >> 24);
intswapU16bitFromArray(byte[] value, int offset)
Reads an unsigned 16 bit integer from an array coming from a device, and returns it as an 'int' 
int v = 0;
v |= ((int) value[offset]) & 0x000000FF;
v |= (((int) value[offset + 1]) & 0x000000FF) << 8;
return v;
inttoInt(byte[] in)
to Int 
int out = 0;
for (int i = in.length - 1; i > 0; i--) {
    out |= in[i] & 0xff;
    out <<= 8;
out |= in[0] & 0xff;
return out;
intparseInt(byte[] b, int start, int end, int radix)
Convert the bytes within the specified range of the given byte array into a signed integer in the given radix . 
if (b == null)
    throw new NumberFormatException("null");
int result = 0;
boolean negative = false;
int i = start;
int limit;
int multmin;
int digit;
...
intparseInt(byte[] b, int start, int end)
Convert the bytes within the specified range of the given byte array into a signed integer . 
return parseInt(b, start, end, 10);
