The ways I've tried to reset my game lead to either not executing the main, or a new black jFrame freezing

I have a blackjack game with a guy that has a reset button in the ActionListener. However, when I use it, much of the program's functionality isn't there. The reset is invoked by:
public class BlackjackGameTable extends JFrame{
JButton stayButton = new JButton("STAY");
JButton hitButton = new JButton("HIT");
JButton resetButton = new JButton("Reset");
JLabel background;
Hand playerhand = new Hand();
Hand dealerhand = new Hand();
JLabel score;
JLabel text;
class DecisionListener implements ActionListener{
public void actionPerformed(ActionEvent a){
if(a.getSource() == hitButton){
CardGame2.hit(playerhand, dealerhand);
playerAddCardToTable(new CardRender2(playerhand.cardlist.get(playerhand.getSize()-1)));
score.setText("Your score: " + playerhand.getScore());
System.out.println("YOU CHOSE HIT! Your Score: " + playerhand.getScore());
}
else if(a.getSource() == stayButton){
System.out.println("YOU CHOSE STAY!");
}
else if (a.getSource() == resetButton){
//I've tried this below
dispose();
new BlackjackGameTable()
//this almost works but the main doesn't execute
//I've also tried:
dispose();
main(null);
//I get a black jframe
//and lastly
dispose();
new BlackjackGameTable().main(null);
}
}
}
public BlackjackGameTable(){
this.setTitle("Blackjack");
background = new TableComponent();
background.setLayout(null);
this.add(background,BorderLayout.CENTER);
this.setVisible(true);
this.setSize(1300,867);

how might I go about getting this reset?

How would I fix this JTextArea formatting error?

I am working on a simple file reader. It reads the .txt file then formats the output and displayed the output in a JTextArea. For some reason, the output does not display correctly. I have given my current code, followed by the text file contents below.
Code
public static JTextArea display = new JTextArea();
public static void main(String[] args) {
// GUI
JFrame frame = new JFrame("Haberdasher");
frame.setSize(450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
JPanel container = new JPanel();
container.setLayout(null);
frame.setContentPane(container);
JScrollPane scroll = new JScrollPane(display);
scroll.setBounds(10, 10, 415, 150);
container.add(scroll);
frame.toFront();
frame.setVisible(true);
// Logic
String path = "src//employees.txt";
boolean endOfFile = false;
String output = "Name" + "\t\t" + "Weekly Sales" + "\t\t" + "Weekly Pay" + "\n";
try {
FileReader fr = new FileReader(path);
BufferedReader br = new BufferedReader(fr);
while (!endOfFile) {
String name = br.readLine();
if(name == null) {
endOfFile = true;
} else {
int sale = Integer.parseInt(br.readLine());
if(name.length() >= 16) {
output += name + "\t" + sale + "\t\t" + "300" + "\n";
} else {
output += name + "\t\t" + sale + "\t\t" + "300" + "\n";
}
}
}
br.close();
System.out.println(output);
display.setText(output);
} catch (IOException e) {
System.out.println(e);
}
}
employees.txt Contents: http://hastebin.com/ijuyedizil.nginx
Current Output:
Expected Output: http://hastebin.com/epesipatot.nginx

Now, the output is fine in the console, but not in the JTextArea.
If you want the text to align like it does on the console need to use a monospaced font
textArea.setFone( new Font("monospaced", Font.PLAIN, 10) );
You may also need to use:
textArea.setTabSize(...);

How to call variables from another class into an ActionListener method?

I would like to apologize in advance I am new to java and don't know very much so stick with me please. I would like to know how to get my character attributes from one ActionListener method in one class to another ActionListener method in another class. I would like to get the inputs from the user about player1 in one class and then use them in the other class. Please help, and I appreciate your time.
public void actionPerformed(ActionEvent event) {
// TODO Auto-generated method stub
if(event.getSource() == create){
Character player1 = new Character( Integer.parseInt(strength.getText()), Integer.parseInt(defense.getText()), Integer.parseInt(health.getText()) , Integer.parseInt(dexterity.getText()));
player1.name = name.getText();
JOptionPane.showMessageDialog(this, "\nName: " + player1.name + "\nHealth: " + player1.health + "\nStrength: " + player1.strength + "\nDefense: " + player1.defense + "\nDexterity: " + player1.dexterity);
dispose();//To close the current window
GameWindow gwindow = new GameWindow();
gwindow.setVisible(true);//Open the new window
}
put into
#Override
public void actionPerformed(ActionEvent event) {
Object source = event.getSource();
Character Goblin = new Character(10, 3, 6, 10);
Character Witch = new Character(2, 7, 3, 20);
Character Zombie = new Character(5, 5, 5, 15);
int damage;
if (event.getSource() == right) {
label1.setText("You have encountered a goblin!");
label2.setText("Do you wish to fight or flee?");
fight.setVisible(true);
flee.setVisible(true);
}
if(event.getSource() == fight) {
System.out.println(player1 + " VS. " + Goblin.name);
while(player1.isAlive() && Goblin.isAlive()){
// player 1 attack
damage = player1.attack(Goblin);
System.out.println(player1.name + " hits " + Goblin.name + " for " + damage + " damage.");
// player 2 attack
damage = Goblin.attack(player1);
System.out.println(Goblin.name + " hits " + player1.name + " for " + damage + " damage.\n");
}
// Check to see who won
if( player1.isAlive()){
System.out.println(player1.name + " wins!");
}
else{
System.out.println("You have perished");
}
}
}

Declare Player1 as public Static member
So it's Value can;t be changed.
and You can use player1 Through the object of that particular Class.
Class First{
//Declare That Character object as a static public here
//Player1;
}
Class Second{
//First Create Object Of that class....
First f = new First(//Parameter For Constructor);
f.Player1;
}

Change your GameWindow constructor like this.
class GameWindow extends JFrame implements ActionListener{
private Character player1;
public GameWindow(Character player1){
this.player1 = player1;
}
#Override
public void actionPerformed(ActionEvent event) {
Object source = event.getSource();
Character Goblin = new Character(10, 3, 6, 10);
Character Witch = new Character(2, 7, 3, 20);
Character Zombie = new Character(5, 5, 5, 15);
int damage;
if (event.getSource() == right) {
label1.setText("You have encountered a goblin!");
label2.setText("Do you wish to fight or flee?");
fight.setVisible(true);
flee.setVisible(true);
}
if(event.getSource() == fight) {
System.out.println(player1 + " VS. " + Goblin.name);
while(player1.isAlive() && Goblin.isAlive()){
// player 1 attack
damage = player1.attack(Goblin);
System.out.println(player1.name + " hits " + Goblin.name + " for " + damage + " damage.");
// player 2 attack
damage = Goblin.attack(player1);
System.out.println(Goblin.name + " hits " + player1.name + " for " + damage + " damage.\n");
}
// Check to see who won
if( player1.isAlive()){
System.out.println(player1.name + " wins!");
}
else{
System.out.println("You have perished");
}
}
}
}
And pass parameter to new contructor.
public void actionPerformed(ActionEvent event) {
// TODO Auto-generated method stub
if(event.getSource() == create){
Character player1 = new Character( Integer.parseInt(strength.getText()), Integer.parseInt(defense.getText()), Integer.parseInt(health.getText()) , Integer.parseInt(dexterity.getText()));
player1.name = name.getText();
JOptionPane.showMessageDialog(this, "\nName: " + player1.name + "\nHealth: " + player1.health + "\nStrength: " + player1.strength + "\nDefense: " + player1.defense + "\nDexterity: " + player1.dexterity);
dispose();//To close the current window
GameWindow gwindow = new GameWindow(player1);
gwindow.setVisible(true);//Open the new window
}

JPanel, List, JFrame

Figured out the problem , Now I just don't know how to fix it .
The problem is when the user clicks Save Button , it saves all the textfields to the correct strings and to the Summary but it doesn't add the JPanel to the ArrayList of Panels .
saveEntryButton.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
String name = nametf.getText();
String username = usernametf.getText();
String password = passwordtf.getText();
String description = descriptiontf.getText();
String summary = "Name: " + name + "\n"
+ "Username: " + username + "\n"
+ "Password: " + password + "\n"
+ "Description: " + description + "\n\n";
JPanel entryPanel = new JPanel();
JLabel entryLabel = new JLabel(summary);
entryPanel.add(entryLabel);
entries.add(entryPanel);
entryFrame.dispose();
mainMenu mmaa = new mainMenu();
mmaa.menuFrame();
}
});
When debugging I saw that the ArrayList entries , was empty (size of 0) .
So that's why nothing is showing on the ViewFrame. Does anyone know how to make a List of JPanels ? Or any other container that is able to Add and Remove JPanels ?

frame won't repaint after adjusting string

I am not sure what I am doing wrong to get my frame to change when I have the user input data and press enter to adjust the string that was set to display on the frame. I am just going to include the code that I feel is applicable since the whole code is pretty long, but if someone would like to see more of something, let me know and I can post more. Thank you for the help!
//adds the Flower data to the Array and list
ActionListener flowerAddAction = new ActionListener(){
#Override
public void actionPerformed(ActionEvent flowerAddAction){
if(flowerAddAction.getActionCommand().equals("Enter")){
Name = NameTxt2.getText();
Colors = ColorTxt2.getText();
Smell = SmellTxt.getText();
ID = (int) IDCmbo.getSelectedItem();
if(((String) ThornCmbo.getSelectedItem()).equals("Yes"))
Thorns = true;
else
Thorns = false;
plants[count] = new Flower(Name, ID, Colors, Smell, Thorns);
displayEntered.setText(displayArray);
count++;
frame.repaint();
frameB.setVisible(false);
}
}
};
enterFlrData.addActionListener(flowerAddAction);
this code above is to add the action to when the user presses enter after inputting data into the textFields and ComboBoxes. Below creates a long string of an array that is created by the input. (If anyone has a better way of displaying an array on a JLabel I'd love to know because I know this is a little sloppy.
//create a string of all values for the array
displayArray = " ";
String displayArraytemp = " ";
for(int n = 0; n < 25; n++){
if(plants[n] != null){
if(plants[n] instanceof Flower){
displayArraytemp = (n + ": " + plants[n].getID() + ", " + plants[n].getName() + ", " + ((Flower)plants[n]).getColor() + ", " + ((Flower)plants[n]).getSmell() + ", Thorny: " + ((Flower)plants[n]).getThorns() + "/n");
}
else if(plants[n] instanceof Fungus){
displayArraytemp = (n + ": " + plants[n].getID() + ", " + plants[n].getName() + ", " + ((Fungus)plants[n]).getColor() + ", Poisonous: " + ((Fungus)plants[n]).getPoisonous() + "/n");
}
else if(plants[n] instanceof Weed){
displayArraytemp = (n + ": " + plants[n].getID() + ", " + plants[n].getName() + ", " + ((Weed)plants[n]).getColor() + ", Edible: " + ((Weed)plants[n]).getEdible() + ", Medicinal: " + ((Weed)plants[n]).getMedicinal() + ", Poisonous: " + ((Weed)plants[n]).getPoisonous() + "/n");
}
else if(plants[n] instanceof Herb){
displayArraytemp = (n + ": " + plants[n].getID() + ", " + plants[n].getName() + ", " + ((Herb)plants[n]).getColor() + ", " + ((Herb)plants[n]).getFlavor() + ", Medicinal: " + ((Herb)plants[n]).getMedicinal() + ", Poisonous: " + ((Herb)plants[n]).getSeasonal() + "/n");
}
displayArray += (displayArraytemp + "/n");
}
}
Below is showing the rest creating the label and includes the main method.
final JPanel p2Base = new JPanel();
displayEntered = new JLabel(displayArray);
//entire constant GUI put together
p2Base.setLayout(new BorderLayout(10,10));
p2Base.add(menuBar, BorderLayout.NORTH);
p2Base.add(p1Right, BorderLayout.EAST);
p2Base.add(displayEntered, BorderLayout.WEST);
public static void main(String[] args) {
frame = new GUI();
frame.setTitle("Plant Database");
frame.setSize(900,700);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}

This looks suspicious to me:
flowerAddAction.getActionCommand().equals("Enter")
If you want this ActionListener respond to pressing the enter button then this will fail since the actionCommand String will not be "Enter". I'm not even sure what it will be, and don't really care, since I usually use ActionListener's for each component and so usually don't test the actionCommand String.
As for your messy array code, consider instead giving your flowers a decent toString() method or method of a similar idea that returns a useful String that can be displayed. That way you can get rid of all of those instanceof operations and have much simpler smaller code.
Edit
I should just shut up and read the API. The action command of a JTextField is the text it contains, unless you set it explicitly.
import java.awt.event.*;
import javax.swing.*;
public class EnterActionCommand {
public static void main(String[] args) {
JTextField field1 = new JTextField(10);
JTextField field2 = new JTextField(10);
// **** set the action command explicitly for field2 ****
field2.setActionCommand("Field 2");
ActionListener actionListener = new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
System.out.printf("action command: \"%s\"%n", e.getActionCommand());
}
};
field1.addActionListener(actionListener);
field2.addActionListener(actionListener);
JPanel panel = new JPanel();
panel.add(new JLabel("Field 1:"));
panel.add(field1);
panel.add(new JLabel("Field 2:"));
panel.add(field2);
JOptionPane.showMessageDialog(null, panel);
}
}
