Sharing variables between 2 custom components. Please help.

Hi,

I'm a beginner in java and I have a problem.
I need to use 2 classes, defined in 2 separate files, in a thisrd, main class.
Actually I copy/paste the 2 classes (are made as swing jpanels with controls, textboxes, combos, etc) in the main class, so in the main class they appear as components.
I need to read a value from one ( a combobox selected item), and use it in the second one.

how could this be done ?

Normally this is done by creating a custom constructor for the components. Send the reference of the objects of the other component to these components with their constructor.

I tried but is not working. what I need is to read a combo box from first component every time when it is updated and use it in second component , when a buton from second component is pushed. I don't know how to make this.
