how to identify the pattern ?

hi i am doining the developer exam from sun..
i just posted this query to developer group too.
i thought why not i ask design gurus too..
i am confused which pattern i describe this as...
I know Swings are implemented as MVC.could some one tell me what pattern is my GUI.i thought its reactor patter.
for checkbox i use comboboxmodel and for tables i use absrtract table model..
i use simple structer for GUI like..please look into a snippet of my GUI structure..

code:
--------------------------------------------------------------------------------
public class ClientGui extends JFrame {
Flight Origin = new Flight(origin1[i]);
destination.addElement(Destination);
}
class Flight {
protected String m_name;
public Flight(String name)
{
}
public String getName()
{
}
public String toString()
{
}
}
public FlightPanel(Vector origin, Vector destination)
{ }
public void actionPerformed(ActionEvent e)
{ //call table; ResultTable (result)
}
}
--------------------------------------------------------------------------------
Table GUI........................

code:
--------------------------------------------------------------------------------
public class ResultTable extends JFrame implements ActionListener
{
}
class ResultTableData extends AbstractTableModel
{ }
--------------------------------------------------------------------------------
This is whole structure of my GUI..so what do i call this as.which patter is it? reactor or delegator patter.
or i say MVC pattern....
please comment on it.any help will be appreciated..

Why no one wanna answer this..
is developer group people are not allowed here..
i just need help..
baiju

Baiju,
This forum has very limited participation and as such, everybody and anybody who cares to post here are welcome. But because there are relatively few active participants here, don't expect answers right away, if at all.
It's a little hard to tell from the code you gave whether or not it conforms to a known pattern. But then again, I am not an expert in patterns. That's why I hang out here at lot, hoping to learn more about them.
All I can say is that event listeners and the Java delegation event model (which your code obviously uses) fall under the Observer pattern. But that's just a small part of the puzzle. Since patterns vary in scope and usage, it is entirely possible for several patterns to co-exist in a design. Perhaps if we saw more of your code, we might be able to help you see if there is a pattern in it or not.
Just curious though, does the Developer exam specify that you need to use a known pattern? Will Sun ask you to explain your design in terms of patterns?
BTW, you might want to re-register yourself to conform to the JavaRanch naming policy.

hi
java developer exam needs a FBN assignment to be completed.
abviously when u make a project/asignment we need to code smart.
to code smart we need to apply design patterns.
I too basicall relized it when i was evaluating the assignment .i did coded but had lot of classes which could have been done more efficiently.
so i applied some patterns to make life easier for all.
but now i could not figute out what design pattern i need to mention like MVC,delegator or reacotr.so i am confused..
here is my sample code.
bascially i have 2 combobox and JTble.
combobox i use Comboboxmodel and i extended the abstracttable mode for Jtable.
class UI{
Flight Origin = new Flight(origin1[i]); //i get all vales and call FLIght
origin.addElement(Origin);
}
class Flight
{
protected String m_name;

public Flight(String name)
{
m_name = name;

}
public String getName()
{
return m_name;
}
public String toString()
{
return m_name;
}
}
class FlightPanel extends JPanel implements ActionListener
{

public FlightPanel(String title, Vector origin, Vector destination,ClientGui app)
{
//i populate the combobox with values
}
public void actionPerformed(ActionEvent e)
{
//here i call the table GUI..
}
}

this is how my table look like same as above ....
public class ResultTable extends JFrame implements ActionListener
{}
class ResultTableData extends AbstractTableModel
{
}
this is how my GUI is..
please do add comments...
baiju

no one for help..

baiju,
To code smart, you need to adhere to OO design principles and apply good programming practices. You will find that design patterns are based on basic OO design principles.
Look around this website: http://www.objectmentor.com for articles about good OO design principles and apply them. Read books like "Elements of Java Style", "Effective Java", "Practical Java", "Java Pitfalls" and books on Java programming idioms and apply the advice in those books.
Also, how could you apply patterns without knowing beforehand what they were?

yeah
In sense u r correct.my problem was at the end i created lot of unnecessary classes.which could have done much easier
if i would have used design pattern.
at the end i did relize it.i had to just apply it ..
but if i would have thought of design patern life would have been much easier..
still in GUI i could not figure it out.i some times feel its obderver,my events are reactor patter ,i know its MVC but still
i am just confused

baiju
