title: Java with JFrame and class interaction
body: <p>I have two classes in the same Package. The package is called main. Main contains two classes a Main class and a Display class. The display class was created to display a GUI with text boxes and buttons. I gave the buttons a listener that fires when the user clicks one of the button. In the main class is a vector of object that i am storing and need to display one a time in the display class' text boxes.</p>
  
  <p>My Question is: can the mouse clicked action call a method in the main class that gathers the needed info an passes that back to a method in the display class to modify those text boxes> Do i need to combine my two classes into one? How would i do within the classes?</p>
  
  <p>From testing i have made the main class extend the display class. I am able to start the display class from here but when i try to call a method in display from main it does nothing. If i try to call a main method from the display class it also seems to do nothing. </p>
