Use of JButton array Java

I am not sure what I am doing wrong. I am trying to create 4 buttons using the arrays and passing the method to the Set Panel class. When I run it I only get one button. Any help would be great. Essentially what I want is a Panel with four buttons, through the use of Methods.
public class SetButtons extends JButton implements ActionListener {
JButton [] buttonArray = new JButton[4];
JButton exitBtn, newGameBtn, checkBtn, clearBtn;
Font myFont = new Font("ink free", Font.BOLD,22);
public SetButtons(){
this.exitBtn = new JButton("Exit");
this.newGameBtn = new JButton("New Game");
this.checkBtn = new JButton("Check Answer");
this.clearBtn = new JButton("Clear");
this.buttonArray[0] = exitBtn;
this.buttonArray[1] = newGameBtn;
this.buttonArray[2] = checkBtn;
this.buttonArray[3] = clearBtn;
for (int i = 0; i < 4; i++){
this.buttonArray[i].addActionListener(this);
this.buttonArray[i].setFont(myFont);
this.buttonArray[i].setFocusable(false);
this.buttonArray[i].setLayout(new FlowLayout());
}
}
#Override
public void actionPerformed(ActionEvent e) {
if(e.getSource() == this){
System.exit(0);
}
}
}
import javax.swing.*;
import java.awt.*;
public class SetPanel extends JPanel {
Font myFont = new Font("ink free", Font.BOLD,22);
SetLabels labels;
SetButtons exitButton;
SetPanel(){
SetButtons btn = new SetButtons();
this.add(btn);
this.setBackground(Color.darkGray);
this.setLayout(new FlowLayout());

StackOverflowError when adding JTextField to the constructor

So I do know what an StackOverflowError is, the problem however is I can't find it here. I am supposed to make a simple GUI with labels, text fields and buttons. One of these buttons is supposed to "clear" the text fields, so I add that by putting text field as an argument in the constructor, but when I actually add the text fields i just get an stack overflow error. Here is the code:
Orders class:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Orders extends JFrame {
public Orders() {
JPanel panel1 = new JPanel();
panel1.setLayout(new GridLayout(4, 2, 2, 2));
JLabel name = new JLabel("Item name:");
JLabel number = new JLabel("Number of:");
JLabel cost = new JLabel("Cost:");
JLabel amount = new JLabel("Amount owed:");
JTextField nameJtf = new JTextField(10);
JTextField numberJtf = new JTextField(10);
JTextField costJtf = new JTextField(10);
JTextField amountJtf = new JTextField(10);
panel1.add(name);
panel1.add(nameJtf);
panel1.add(number);
panel1.add(numberJtf);
panel1.add(cost);
panel1.add(costJtf);
panel1.add(amount);
panel1.add(amountJtf);
JPanel panel2 = new JPanel();
JButton calculate = new JButton("Calculate");
JButton save = new JButton("Save");
JButton clear = new JButton("Clear");
JButton exit = new JButton("Exit");
panel2.add(calculate);
panel2.add(save);
panel2.add(clear);
panel2.add(exit);
OnClick action = new OnClick(exit, clear, save, calculate, nameJtf, numberJtf, costJtf, amountJtf);
exit.addActionListener(action);
this.setTitle("Otto's Items Orders Calculator");
this.add(panel1, BorderLayout.NORTH);
this.add(panel2, BorderLayout.SOUTH);
this.setSize(400, 200);
this.setDefaultCloseOperation(EXIT_ON_CLOSE);
this.setLocationRelativeTo(null);
this.setVisible(true);
}
public static void main(String[] args) {
new Orders();
}
}
OnClick class :
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class OnClick extends Orders implements ActionListener {
private JButton exitModify = null;
private JButton clearModify = null;
private JButton saveModify = null;
private JButton calculateModify = null;
private JTextField nameModify = null;
private JTextField numberModify = null;
private JTextField costModify = null;
private JTextField amountModify = null;
public OnClick (JButton _exitModify, JButton _clearModify, JButton _saveModify, JButton _calculateModify, JTextField _nameModify, JTextField _numberModify, JTextField _costModify, JTextField _amountModify) {
exitModify = _exitModify;
clearModify = _clearModify;
saveModify = _saveModify;
calculateModify = _calculateModify;
nameModify = _nameModify;
numberModify = _numberModify;
costModify = _numberModify;
amountModify = _amountModify;
}
public void actionPerformed(ActionEvent e) {
Object o = e.getSource();
if (o == this.exitModify) {
System.exit(0);
} else if (o == this.clearModify) {
amountModify = null;
nameModify = null;
costModify = null;
numberModify = null;
}
}
}
As soon as I add nameJtf I get this error.

How to remove existing panel before adding new one

I am learning Java and working on a project. I want to add a new panel as the button is clicked. It is working, but if user clicks button again it adds the panel again. I want to remove the existing panel before adding new one. I have tried remove(westPanel); revalidate(); at the start of my actionPerformed method, but its not working.
Can someone please help?
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class MyJpanel extends JPanel implements ActionListener
{ //declaring some buttons
private JButton newAccountButton, deleteAccountButton, searchButton, showButton, depositButton, withdrawButton;
protected JPanel westPanel, panel;
JLabel message = new JLabel("Please Use Buttons For Interation");
public MyJpanel()
{
newAccountButton = new JButton("Create Account");
deleteAccountButton = new JButton("Delete Account");
searchButton = new JButton("Search Account");
showButton = new JButton("Show Accounts");
depositButton = new JButton("Deposit");
withdrawButton = new JButton("Withdraw");
setBackground(Color.GRAY);
add(newAccountButton);
add(deleteAccountButton);
add(searchButton);
add(showButton);
add(depositButton);
add(withdrawButton);
newAccountButton.addActionListener(this);
}
#Override
public void actionPerformed(ActionEvent e)
{ westPanel= new JPanel();
if (e.getSource()==newAccountButton)
{ getRootPane().remove(westPanel);
revalidate();
JLabel accountNumber = new JLabel("Account Number");

westPanel.setLayout(new GridLayout(4,2));
westPanel.setBackground(getBackground());

I need help figuring out why my clear button code does not work

I am working on a project for my Java class and cannot get my clear button to work. More specifically, I am having an issue implementing Action and ItemListeners. My understanding is that I need to use ActionListener for my clear button, but I need to use ItemListener for my ComboBoxes. I am very new to Java and this is an intro class. I haven't even begun to code the submit button and ComboBoxes and am a little overwhelmed. For now, I could use help figuring out why my clear function will not work. Any help is greatly appreciated. Thanks in advance.
Here is my updated code after suggestions:

Add following line
clearButton.addActionListener(new clrButton());
class clrButton implements ActionListener {
public void actionPerformed(ActionEvent e) {
// clearButton.addActionListener(this); Comment it
// if(e.getSource() == clearButton){-> this line don't need.
firstName.setText("");
lastName.setText("");
Address.setText("");
City.setText("");
}
}

You are doing good. But just place the following code
clearButton.addActionListener(new clrButton());
Before and outside of class clrButton
Also try placing these statements outside of class subButton
submitButton.addItemListener(new subButton());
Service.addItemListener(new anotherClass());
numTrees.addItemListener(new anotherClass());
howOften.addItemListener(new anotherClass());

You need to add actionlistener to your buttons. so, the action events will be propogated to the listener where you do your logic of the action. so, you have to addActionListener to your button
clearButton.addActionListener(new clrButton());
i.e in your init() method
clearButton = new JButton("Clear");
clearButton.setPreferredSize(new Dimension(100,30));
//add this below line to add action listener to the button
clearButton.addActionListener(new clrButton());
Onemore line to be removed is clearButton.addActionListener(this); from your action performed method

Adding a TextField to a program

I am making a better version of an application that was given to me. I still need to have the same components as the program that was given to me, I just need to reorganize it. I was also told not to copy any of the original code and do it from scratch. The first screenshot shows the textfield I need to add to my program from the original program. The second screenshot is my program. I am not sure if a JTextField would be best for this. My code is below. I have tried to add a JTextField with a JLabel and center it but when I run the program it covers everything else in the program and only shows a little white box.
