How do I count the number of wins for each, X and O for my program in java?

So I've been trying to figure out a way to count each time someone wins in a tic tac toe GUI game I am making. I already made methods to check the tic tac toe board for any winning combinations for either X or O. I am just stumped on how I could count each time the checkWinsX and checkWinsO are called. I tried to make another method that would add a point to either X or O, but I kinda failed at that lol.
public class ticTacToeFrame extends javax.swing.JFrame {
int turn = 0; //Deterines the turn
int winsX; //Tracks total wins for X
int winsO; //Tracks total wins for O
public ticTacToeFrame() {
initComponents();
}
public void clearAll() {
ulBUT.setText("");
umBUT.setText("");
urBUT.setText("");
mlBUT.setText("");
centerBUT.setText("");
mrBUT.setText("");
llBUT.setText("");
lmBUT.setText("");
lrBUT.setText("");
statusTF.setText("");
}
////////////////////////////////////////////////////////////////////////
// I tried to make something of this sort multiple times here to count the checkWins, and so far this is the one that would seem to start off the best in my head
////////////////////////////////////////////////////////////////////////
public static int wins() {
int winsX = 0;
int winsO = 0;
}
public void checkWinX(int wins) {
//Top row horizontal check for winning
if (ulBUT.getText().equals("X") && umBUT.getText().equals("X") && urBUT.getText().equals("X")) {
statusTF.setText("X Wins Horizontally In The Top Row!");
}
//Middle row horizontal check for winning
else if (mlBUT.getText().equals("X") && centerBUT.getText().equals("X") && mrBUT.getText().equals("X")) {
statusTF.setText("X Wins Horizontally In The Middle Row!");
}
//Bottom row horizontal check for winning
else if (llBUT.getText().equals("X") && lmBUT.getText().equals("X") && lrBUT.getText().equals("X")) {
statusTF.setText("X Wins Horizontally In The Bottom Row!");
}
//Diagonal check for winning
else if (ulBUT.getText().equals("X") && centerBUT.getText().equals("X") && lrBUT.getText().equals("X")) {
statusTF.setText("X Wins Diagonnaly!");
}
else if (urBUT.getText().equals("X") && centerBUT.getText().equals("X") && llBUT.getText().equals("X")) {
statusTF.setText("X Wins Diagonnaly!");
}
}
public void checkWinO() {

I have to tell you you are going about this all wrong. Start with a GameModel
public class TicTacToeModel {
Boolean[][] board; //use Boolean class rather than boolean primative so you can set board spaces that haven't been taken yet null
public void setSpace (int x, int y, boolean isX) throws SpaceTakenException { ... }
public boolean getSpace(int x, int y) { ... }
public Boolean calculateWinner() { ... } // calculate if there's a winner, and return its Boolean value if so. Otherwise null
}
Once that's done and working, you can adapt a GUI to your model.

In your wins() method, you could pass in a parameter indicating X or O and increment the respective counter variable.
For example:
public int win(int player) {
if(player == 0) {
winsX++;
}
else {
winsY++;
}
}
And then call this every time you check and find that a player has won.

Shuffling the images

I've made a picture puzzle game. actually I use Netbeans 8.2 GUI Builder to create the game, I have made Timer and move.
But I am confused how to shuffle the images. I've searched on various sites but it did not help.
This is my code:
package projetu;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.ImageIcon;
import javax.swing.Timer;
import static projetu.fasil.cont;
public class t02 extends javax.swing.JFrame {
static int cont = 0;
int i = 0;
private Timer timer;
private int currentSegundo = 0;
private int currentMinuto = 0;
private int currentHora = 0;
private int velocidade = 1000;
public t02() {
initComponents();
b9.setVisible(false);
}
public void contamuda() {
txtconta.setText(String.valueOf(cont++));
}
private void iniciarContagem() {
ActionListener action;
action = new ActionListener() {
public void actionPerformed(ActionEvent e) {
currentSegundo++;
if (currentSegundo == 60) {
currentMinuto++;
currentSegundo = 0;
}
if (currentMinuto == 60) {
currentHora++;
currentMinuto = 0;
}
String hr = currentHora <= 9 ? "0" + currentHora : currentHora + "";
String min = currentMinuto <= 9 ? "0" + currentMinuto : currentMinuto + "";
String seg = currentSegundo <= 9 ? "0" + currentSegundo : currentSegundo + "";
tempu.setText(hr + ":" + min + ":" + seg);
}
};
this.timer = new Timer(velocidade, action);
this.timer.start();
}

First: You are missing the == in enterActionPerformed. Use two = signs.
Second: If I understood correctly, everytime there's a '-', the number gets negated. Which is happening after the first number is written.
9-5 gives you 4 because you are negating the first number and adding it to the second:
(-9)+5 =-4
The error is in the following code, when you press the '-' button, you are doing 0-valueEntered.
private void minusActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
fNums = fNums - Double.parseDouble(display.getText());
display.setText("");
sub = true;
}

if(add == true){
sNums = fNums + Double.parseDouble(display.getText());
display.setText(String.valueOf(sNums));
fNums = 0;
add = false;
} else {
`
`if(sub == true){
sNums = fNums + Double.parseDouble(display.getText());
display.setText(String.valueOf(sNums));
fNums = 0;
sub = false;
}
}

You can check out my MathExpressionEvaluator repository from Github, as it can easily evaluate simple math expressions.
You can pass it a string expression from your calculator and display the answer that you get from it easily.

Change the Minus listener to
private void minusActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
fNums = Double.parseDouble(display.getText()); <----------
display.setText("");
sub = true;
}
and enter action performed as
private void enterActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your enter code here:
if(add == true){
sNums = fNums + Double.parseDouble(display.getText());
display.setText(String.valueOf(sNums));
fNums = 0;
add = false;
} else {
if(sub == true){
sNums = fNums - Double.parseDouble(display.getText()); <----------
display.setText(String.valueOf(sNums));
fNums = 0;
sub = false;
}

How to transform my toggle button value to int

Here is my simple calculator code.Im trying to add this code something special.I want this program to: it will only use 2 even numbers or 2 odd numbers for the four arithmetical operations. For instance,If user is trying to click an even number and a odd number at the same time,my code will warn like "You can click 2 even numbers or 2 odd numbers".How can I use the values that clicked by toggle buttons as int and use if(value%2==0) statement?

JToggleButton has two states , test with JToggleButton.isSelected
after code executed is required to reset state of JToggleButton.setSelected(false), because Mouse / Key Events toggle with JToggleButton
JToggleButton (JOptionPane.showMessageDialog(this, "You cant click 3 buttons at the same time..");) isn't proper JComponent for Calculator (keys 0-9, + - =), use JButton instead, there are various and different ways how to do it an properly, start with ActionCommand or put/getClientProperty
for better help sooner post an SSCCE

For a simple calculator, I'd recommend using JButtons as opposed to JToggleButtons. With JButtons, you could simply use:
StringBuilder intbuilder = new StringBuilder();
int firstnumber;
int secondnumber;
String operation;
button5.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e)
{
intbuilder.append("5");
}
});
multiplybutton.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e)
{
firstnumber = Integer.parseInt(intbuilder.toString());
operation = "*";
}
});
And once the equals sign is pressed, just have perform the operation on the two numbers depending on the String operation.

How to stop calling a method from another method in java?

I have a calculator code and the problem is:
public void valueCheck(String value,JToggleButton button) {
if(values.size()>2)
{
processValue(value);
button.setSelected(false);
JOptionPane.showMessageDialog(this, "You cant click 3 buttons at the same time..");
}
}
There is a method valueCheck and:
public boolean evenOdd(JToggleButton buton)
{
if(values.size()==2)
{
System.out.println((String)values.get(0));
System.out.println((String)values.get(1));
String number1 = new String(values.get(0));
String number2 = new String(values.get(1));
if(evenNumbers.contains(number1))
{
if(evenNumbers.contains(number2))
{
processValue(number1);
processValue(number2);
}
else if(oddNumbers.contains(number2))
{
buton.setSelected(false);
JOptionPane.showMessageDialog(this, "You cant click an even and an odd number at the same time..");
}
}
else if(oddNumbers.contains(number1))
{
if(oddNumbers.contains(number2))
{
processValue(number1);
processValue(number2);
}
else if(evenNumbers.contains(number2))
{
buton.setSelected(false);
JOptionPane.showMessageDialog(this, "You cant click an even and an odd number at the same time..");
}
}
}
return false;
}
there is a method evenOdd.
My problem is: I dont want valueCheck method to run for evenOdd method.When evenOdd method runs valueCheck must be stopped calling.Is there a event to do this?I want to stop calling valueCheck when evenOdd is running
Here is my whole code.

Your problem is not related to multithreading. Multithreading involves multiple threads, thus the word itself. In your situation, what you want to do can be achieved with simple if-else statement and proper return value from the involved methods.
I see that your method evenOdd() already returns boolean. You can take advantage from that. After displaying your error message in evenOdd(), make it to return false. Then, when the toggle button is pressed, test if evenOdd() returns true then call valueCheck(), else, if it returns false (error message was displayed), do not call it.
if(evenOdd(jToggleButton1))
valueCheck("1", jToggleButton1);
Also, your current method names are confusing. Try playing with the way you name your methods. Methods should be named in such way that when you see it, you already know what it does.
