Jbutton Is Disappearing Even Though I call .setVisible(true)

I am making a basic platformer game and I need to make it so that every time you jump all the platforms that are below where you jumped disappear and every platform above moves down. It is still in development so just ignore some of the things that are commented out and the messy mode.
Basically, my problem is that when I try to clear all the platforms below the one that you clicked it works fine using this code:
for(int i = 0; i < platforms.length; i++) {
if(platforms[i] == null) {
continue;
}
if(parameters[i][1] > y) {
platforms[i].setVisible(false);
}
}
However later when I try to use .setvisible(true) on the platform that you clicked it doesn't work. Here is the full code:

Problems with repaint() method in java

I'm new to Java and trying to make a simple Player vs. Computer "Tic-Tac-Toe" game using Swing. In the code I use paintComponent() method to paint certain components and call the repaint() method after the player or computer plays. The problem is that, the game freezes after the third (sometimes the second) time I click the mouse. In GameWindow class I create the instance of Map class.
public class GameWindow extends JFrame{
private final int sizeX = 3;
private final int sizeY = 3;
public GameWindow(){
setLocation(400,150);
setSize(406, 452);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
setResizable(false);
Map map = new Map(sizeX, sizeY);
add(map, BorderLayout.CENTER);
JPanel bottomPanel = new JPanel();
bottomPanel.setLayout(new GridLayout(1, 2));
add(bottomPanel, BorderLayout.SOUTH);
Button newGame = new Button("Новая игра");
newGame.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
System.out.println("Начинаем новую игру");
}
});
Button exit = new Button("Выход");
exit.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
System.exit(0);
}
});
bottomPanel.add(newGame);
bottomPanel.add(exit);
setVisible(true);
}
}
Here is the listener for the mouse click in the Map class:
public class Map extends JPanel {
private final int sizeX;
private final int sizeY;
private int cellWidth;
private int cellHeight;
private int cellX = -1;
private int cellY = -1;
private String lastPlayer = "nobody";
private String[][] table = new String[3][3];
public Map(int sizeX, int sizeY) {
this.sizeX = sizeX;
this.sizeY = sizeY;
setBackground(Color.WHITE);
for (int i = 0; i < table.length; i++) {
for (int j = 0; j < table.length; j++) {
table[i][j] = "empty";
}
}
addMouseListener(new MouseAdapter() {
#Override
public void mouseReleased(MouseEvent e) {
super.mouseReleased(e);
cellX = e.getX() / cellWidth;
cellY = e.getY() / cellHeight;
if (!winOrDraw()) {
boolean playerProgress = playerProgress();
if(playerProgress) {
botProgress();
}
}
}
});
}
Both in playerProgress() and botProgress() methods I call repaint() method to add new components to the screen. I can't really find out what is the problem in this code and why the program freezes after actually 6th call of repaint() method?
Here are winOrDraw(), playerProgress() and botProgress() methods:
private boolean winOrDraw(){
for (int i = 0; i < table.length; i++) {
if(table[i][0] == table[i][1] && table[i][1] == table[i][2] && !table[i][0].equals("empty")) return true;
else if(table[0][i] == table[1][i] && table[1][i] == table[2][i] && !table[0][i].equals("empty")) return true;
else if(table[0][0] == table[1][1] && table[1][1] == table[2][2] && !table[0][0].equals("empty")) return true;
else if(table[2][0] == table[1][1] && table[1][1] == table[0][2] && !table[2][0].equals("empty")) return true;
}
int i, j = 0;
for (i = 0; i < table.length; i++) {
for (j = 0; j < table.length; j++) {
if(table[i][j].equals("empty")) break;
}
}
if(i == table.length && j == table.length) { lastPlayer = "nobody"; return true; }
else return false;
}
private boolean playerProgress(){
if(!table[cellY][cellX].equals("empty")){
System.out.println("This cell is not empty");
return false;
} else {
lastPlayer = table[cellY][cellX] = "player";
repaint();
return true;
}
}
private void botProgress(){
do{
if(winOrDraw()){
switch (lastPlayer) {
case "player":
System.out.println("You won!");
System.exit(0);
case "bot":
System.out.println("Bot won");
System.exit(0);
default:
System.out.println("Draw");
System.exit(0);
}
}
Random random = new Random();
cellX = random.nextInt(2);
cellY = random.nextInt(2);
if(table[cellY][cellX].equals("empty")) {
lastPlayer = table[cellY][cellX] = "bot";
break;
}
}while (!table[cellY][cellX].equals("empty"));
System.out.println("Bot's turn");
repaint();
}

You are adding your Swing components directly to the JFrame-AWT-container. You should not do that. Instead you should do this:
JPanel panel = new JPanel();
myFrame.setContentPane(panel);
panel.setLayout(...)
panel.add(...);
panel.validate();
This should solve your problem.

Win check not working in TicTacToe game?

A for loop to check for the rows.
A for loop to check for the columns.
Two if statements to check for diagonals.
The win method does not return true at all. Is there something wrong with the && operators?

btns[i][j] is a JButton so it will never be equal to a String.
You should replace each method call of the form btns[i][0].equals("X") with something like btns[i][0].getText().equals("X").
Beside that, your win method only checks if the "X" player won. What about the "O" player?

Java creating a new frame

Your constructor requires you to pass in an existing TicTac as a parameter. In the code you show, you're trying to create a TicTac without doing so.
As #MadProgrammer points out, requiring a TicTac to create a TicTac creates something of a catch-22 situation: How can you ever create one without having one first? If, for some reason, you do need to create a TicTac with a reference to an existing TicTac, you need to create an additional constructor with no parameters (as your compiler is suggesting) to create the first one:
public TicTac() { }
(more accurately, your constructor can take parameters, it just cant require a TicTac):
class TicTac {
public TicTac(int size) { }
public TicTac(TicTac otherTicTac) { }
...
}
//elsewhere:
TicTac first = new TicTac(5); //or just TicTac first = new TicTac()
TicTac second = new TicTac(first);
However, I'm guessing that you don't really need a TicTac(TicTac otherTicTac) constructor (if so, tell me why), and that you're trying to do so as a result of a misunderstanding about how constructors work - in which case this might be a helpful read, for starters.

How to use a JTextField in more than one class

I have 3 classes for Tic Tac Toe.
Class 1: This is the main class and it hold the button and such
Class 2: The game itself calculates score and such
Class 3: Displays the score from class 2
I am trying to get the score from class 2 and display it in class 3

As discussed in your previous similar question from 30 min ago:
Use one JFrame. The other window should be a JDialog, although here a non-modal JDialog.
Use a getter method to allow one class to get the score String from another class.
The tricky part here that was not discussed as we did not have enough information at the time, is knowing when to pass the information to the Score JDialog. Here your main GUI should hold an instance of the Score JDialog, give this JDialog a setter method that would allow the main GUI to set the Score's score JTextField when the actual score changes.
