Parsing byte array containg fields of unknown length

Question

I am parsing in Java a byte array having the following specification:

Trace data format:
    - 4 bytes containing the Id.
    - 4 bytes containing the addres         


        

Answer 1

Assuming the first and last name are null-terminated you would do it like this:

int firstNameLength = 0;
while(firstNameLength<32) {
    if(theArray[firstNameLength]=='0') break;
    firstNameLength++;
}
int lastNameLength = 0;
while(lastNameLength<32) {
    if(theArray[8+firstNameLength+1+lastNameLength]=='0') break;
    i++;
}
String firstName = new String(theArray).substring(8,8+firstNameLength);
String lastName = new String(theArray).substring(8+firstNameLength+1,8+firstNameLength+1+lastNameLength);
