title: Java: Passing Variables across classes
body: <p>This is probably a really simple problem, but I can't figure out how to do it.</p>
  
  <p>I have a GUI class with a listener which takes variables from comboboxes and sliders. I need it to pass these variables into a method in another class which will run on an object in that class.</p>
  
  <p>How can I do this?</p>
