Hey guys
greetings

I'm having problems to update a JList, the numerical values ​​that are in the JList are variables of other classes, and I would like that when I alter the value of these variables in other classes, and pressed the button "Refresh" in class FrameTeste the data in the JList would be updated according to the changes I made in the other classes, I created an example of two different classes of variables with different values ​​and a class that is the frame, it has a JList and button "Refresh",

Exemple :

![enter image description here][1]


![enter image description here][2]


And the Frame Class :

You should use ListModel for the JList, so the data gets updated automatically.

Did you check out the API docs? It has an example of how the data is wrapped inside a model.
Almost all swing components have a How to use xxx linked on the API. Check out the list version here http://docs.oracle.com/javase/tutorial/uiswing/components/list.html
