Truoble with recognised custom event handler class?

[andrew beales]

Hi I am doing my project re-engineering some code I am practically a java beginner.I find that my call to my Buttonhandler class + ComboBoxHandler class doesn`t compile.Where`s my trouble?
I have line like this in methods to a class
btInsert.addActionListener(new ButtonHandler ());
in methods to a class
class ButtonHandler implements ActionListener{
public void actionPerformed(ActionEvent e){
Do I need to instantiate the class in main How?
Do I need to create object reference of Handler class? How?
Thanks

Hi Andrew,
Welcome to JavaRanch. You probably need to show us some code and the list the error that the compiler is giving you. That way we might be able to guide you.

[andrew beales]

My Errors are appearing at call to a customer handler class.At the end of each panel there are components said to listen for event and send to my handler classes
cbName1.addItemListener(new ComboBoxHandler());
"Addressbook.java": Error #: 300 : class ComboBoxHandler not found in class Addressbook at line 542, column 31
How do I make these recognisable when asked to make reference to class in these events.
Should I make a seperate file for the all the handling of events on tab forms listened for.And create get methods for each field?
And Seperate file for data actions.
Thanks!!

Well Andrew, I think you have set a new record for longest code post at JavaRanch Man that's over 1500 lines of code. There are syntax errors that I am having trouble with since a lot of the code has been commented out. If you did not write this (and even if you did) this is not a great example of how to write a java program. In a nutshell you have some misplaced curlies { }. You will need to carefully track them down. Do you know whether or not ButtonHandler and ComboBoxHandler are inner classes of Addressbook? My instincts tell me that they are. If someone else wrote this and if you can get in contact with them, that would be a preferred course of action to find out what's going on. If not, you may need to go thru it slowly and figure it yourself, especially the code that has been commented out.

I think the buttonhandler and combo box handler are inner classes I tried re compile with only error That each attempt to add new of buttonhandler or comboboxhandler are not present to the complier where do i initialise these?
Thanks
