the easiest solution is
byte[] buf;
int i = buf[pos] << 24 | buf[pos+1] << 16 | buf[pos+2] < 8 | buf[pos]

'- Class -
 public final int readInt() throws IOException
Reads a signed 32-bit integer from this data input stream. This method reads four bytes from the underlying input stream. If the bytes read, in order, are b1, b2, b3, and b4, where 0 <= b1, b2, b3, b4 <= 255, then the result is equal to:

(b1 << 24) | (b2 << 16) + (b3 << 8) +b4'
