Direct Known Subclasses:

Ex01_TableUI

public abstract class TableUI

extends javax.swing.JFrame

When instantiated, calls abstract mehod createExercise(). createExercise() must generate the JInternal Frames to display the exercise, then create the GUI, then create the truth table and Checker object that verifies the student input.
