Problem with Methods

[Ed]

I have a Class (class PublishStats) containing 2 methods. Method 1
(UpdateFields) formats text and inserts it into a DefaultStyledDocument
named, for example "wage1". Method 2 (PublishStats) uses a gridbagLayout to
display "wage1". This does not work opviously because wage1 being in method
1 is not availble to code in method 2.

Can someone suggest how I can overcome my problem? Is there a Global option
for a DefaultStyledDocument or something like that? Or is there a way to
call an object in method 1 from method 2? Help please! (There will be 25 of
these entries.)

You need to appreciate the difference between local variables (those
declared inside a method) and instance variables (those declared outside
the method). Any variable that needs to exist from one method call to
another should be an instance variable. Note that this is in no way
'Global' - it is just the way objects encapsulate their state.

Perhaps you can make wage1 be a field of the PublishStats class so that
method 1 and method 2 can both access it. Hard to say if this will yield a
good OO design without seeing the rest of your code.
