WebWe can use another approach without bit shift to convert bytes to short without shift by using java.nio.ByteBuffer. ByteBuffer bb = ByteBuffer.allocate(2); bb.order(ByteOrder.LITTLE_ENDIAN); bb.put(nTempByteArr[1]); bb.put(nTempByteArr[0]); short shortVal = bb.getShort(0); and we can use the get function of ByteBuffer will help … WebBut I need to convert them into an usable int variable. For example, 02 00 00 00 = 2 So far, I have this code to convert the first 2 bytes: (I used FileStream.Read to store the raw datas into a buffer variable) int num = ( (buffer [5] << 8) + buffer [4]); But it will only convert the first two bytes. (02 00 in the example, not 02 00 00 00)
