around this issue setUpButton is a custom method of ButtonDefault not JButton. Therefore the array declaration should be
code :
private ButtonDefault[][] buttons = new ButtonDefault[ROWS][COLUMNS];

it helps some times I'm working on a simple Java GUI, but an error came out about abstract methods. I marked the codes that has an error with a comment ERROR - etc. The interface class is at the bottom, which also has an error about cannot find symbol. It is marked.
code :
public interface ActionListener {

    public void actionPerformed(ActionEvent e);
import java.awt.event.ActionEvent;

public interface ActionListener {

    //ERROR - Cannot find symbol
    //symbol: class Action Event
    public void actionPerformed(ActionEvent e);
import java.awt.event.*;

public abstract class OurActionListener implements ActionListener {

    public abstract void actionPerformed(ActionEvent e);

around this issue This is my source code for a tic tak toe game I am trying to make, what I would like to happen is for a player to press a Jbutton then have the button disabled. I am aware that the command is setEnbale(false) in order for it to lock, but it is not working for me. I have 9 buttons with action listener assigned to them. The program is able to distinguish between player 1 and 2 through the action listener. But when I try to lock the cells as well the " error : can not find symbol some up. " come up. What exactlyam I doing wrong? , Use,
whatPlayer.setEnabled(b) not whatPlayer.setEnable(b)

I hope this helps . For as far as I can see the problem is in your constructor and not in your setters. Parameters and used names don't match -> nh is nHours ( in params ) and w = wages (in params )
Change to constructor should be made to:
code :
public PTEmployee(String name, String ssn, String position, Date dateOfBirth,
                 float pay, int nHours, float wages)
    this.nHours = nHours;
    this.wages = wages;
    pay = 0;
