Question

I have following data fields:

int iData1 = 100;   
int iData2 = 5000;
float fData3 = 80.5f;
float fData4 = 100.1f;
String str1 = "BBBB";   

Sending data as byte array as below:

ByteBuffer buf=ByteBuffer.allocate(BUF_SIZE);  
buf.order(ByteOrder.BIG_ENDIAN);
buf.putInt(bData1);
buf.putInt(iData2);
buf.putFloat(fData3);
buf.putFloat(fData4);
buf.put(str1.getBytes());
sendBytes(buf.array());

To parse the byte array received, I can get each field a follow:

iData1 = bbf.getInt();
iData2 = bbf.getInt();
iData3 = bbf.getInt();
fData3 = bbf.getFloat();
fData4 = bbf.getFloat();

But how to get the string data field (str1) in the array received?
Any hint would be highly appreciated.
Thanks!

Answer 1

Put the length of the string before the string. Then read the string in two steps:

sDataLen = bbf.getInt();
bbf.get(sData5, 0, sDataLen);
