title: Access a private variable of the super() class in Java - JChart2D
body: <p>I have extended a class in Java that has a private variable that I want to get the value of before it is changed. There are no methods to access this variable in the super class. I have tried <code>super().m_zoomArea</code> (the variable is in the <code>ZoomableChart</code> class of jChart2D). The variable is updated when the <code>mouseDragged</code> method is called. I have overridden this method and would like to get the value of the variable before it is updated.</p>
