Initializing A ResultSet
by DevX Pro
I am building a prototype but am trying to make the code as reuseable
as possible. To test the prototype, I need to simulate a ResultSet
being returned from a database. When my backend program simulating a
database tries to add columns into the ResultSet, I get error
messages that the ResultSet has not been initialized, which is true.
How would I go about initializing this ResultSet given that I have no
database and am currently reading a file and trying to populate the
ResultSet using methods within ResultSet.
