Is there any tutorial for SAP Java Backend Development?

Question

Hi everyone,
I am following the "How To - Part 1: Build an Agentry based app from scratch connecting to a SAP ERP back-end" to learn Agentry by myself.
There are some Java code when creating the Steplet, StepHandler and Bapi that I dont understand. I would like to know if there is any document or tutorial to learn how to write  such Java code. I already know the Agentry stuffs like fetch, step, etc.
For example, why do we need the processResult or setParameter method? Why do we need JCO.Table? Where is the table "ET_FLT_SCHEDULE"
public class FlightScheduleBapi extends AbstractFetchBAPI{
public User user = null;
public FlightScheduleBapi(User u, GregorianCalendar lu) throws Exception {
super(u, lu);
user = (User) u;
@Override
public ArrayList<SAPObject> processResults() throws Exception {
ArrayList<SAPObject> spfliTab = new ArrayList<SAPObject>();
JCO.Table _sTab = _tables.getTable("ET_FLT_SCHEDULE");
int rows = _sTab.getNumRows();
for(int i = 0; i<rows; i++)
_sTab.setRow(i);
FlightSchedule spfliLine = new FlightSchedule(_sTab);
spfliTab.add(spfliLine);
  return spfliTab;
@Override
public void setParameters(SAPObject obj) throws Exception {
  super.setParameters(obj);
try {
  } catch (Exception e) {
user.rethrowException(e, true);
Thank you very much.

Anyone can help me out of this?
I am looking for AbstractFetchBAPI but there is no information about it.
I found JCO Client Connection and JCO getTable to access SAP tables. Can I use this way in Agentry App?
Thanks.
