title: How to make int variable visible to other class from GUI JButton
body: <p>I'm trying to access the int <code>myInt</code> in this GUI form class from another class. The method does pass the input variable to <code>myInt</code> properly but I have not been able to make it visible to the other java file.  I have been reading about scope and class declarations and have been able to muddle along up until now, but I am doing something wrong here. Nothing I have tried has worked.</p>
