public class CyberPet
    private boolean isEating = true;    // CyberPet's state
    private boolean isSleeping = false;
    private boolean isThinking = false;
    private String name = "no name";    // CyberPet's name
    public CyberPet (String str)        // Constructor method
        name = str;
    public void setName (String str)    // Access method
        name = str;
    } // setName()
    public String getName()
        return name;           // Return CyberPet's name
    } // getName()
    public void eat()          // Start eating
        isEating = true;       // Change the state
        isSleeping = false;
        isThinking = false;
        return;
    } // eat()
    public void sleep()        // Start sleeping
        isSleeping = true;     // Change the state
        isEating = false;
        isThinking = false;
        return;
    } // sleep()
   public void think()
        isThinking = true;
        isSleeping = false;
        isEating = false;
        return;
    public String getState ()
        if (isEating)
            return "Eating";     // Exit the method
        if (isSleeping)
            return "Sleeping";   // Exit the method
        if (isThinking)
            return "Thinking";
        return "Error in State"; // Exit the method
    } // getState()
    public String toString()
        return name + " is " + getState();
} // CyberPet
* Description: This apply provides a graphical user
*  interface to the CyberPet class. The interface consists
*  of two Buttons that can be clicked to tell the CyberPet
*  to eat or drink, and a TextField which reports the
*  CyberPet's state.
*  The interface is initialized in the init() method and
*  user actions are handled in the actionPerformed() method.

Answer 1

I'm still not sure if I understand your initial question.
// Here's an example of adding an action listener
nameTextField.addActionListener(
   new ActionListener() {
      public void actionPerformed(ActionEvent e) {
         // Code goes here
         // if nameTextField is validated then ...
);
