I can't find the field recordNumber in the binary data file created by the data convertion tool, where does this field come from?
in Data class, in the find(
String toMatch) method,the comment says toMatch is the key field value to match upon for a successful find, for this assignment, the key field is the record number field. In the find method body, I think the Flight number field is compared to the toMatch parameter, not the record number is compared to toMatch,am I right?
another question, why isn't the writeRecord method sychronized?
Could you help me please? thanks!!
