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!");

}
//Diagonal check for winning

}
else if (urBUT.getText().equals("X") && centerBUT.getText().equals("X") && llBUT.getText().equals("X")) {

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.

How to delete text from a JTextField when you press a JButton (JAVA)

My program has to print messages in the JTextField when the Resume Producers button is pressed, and it needs to delete the messages when the Resume Consumers is pressed.
The thing is that I don't know how to delete the messages when the Resume Consumers is pressed.
Code:
package buffer;

}

}

{

{

{
wait();
} catch (InterruptedException ex) { }
}
pass.look();
full=true;
message=msg;
list.add(message);
for(int i=0; i<list.size(); i++){
content=content+list.get(i);
}
tf.setText(content);
notifyAll();
}
public synchronized String receivesMessage()

{

The thing is that i don't know how to delete the messages when the Resume Consumers is pressed
You add an ActionListener to the button. In the ActionListener you reset the text. See the section from the Swing tutorial on How to Us Buttons for more information and examples. Or, there is also a section on How to Write an ActionListener.
You can replace the text in the text field by using:
textField.setText(...);

Example #1 (Requires Java 8+):
button.addActionListener(e -> textField.setText(""));
Example #2:
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
textField.setText("");
}
});
In both cases, the textField will need to have been declared as final.

RMI ClassCastException to remote interface

Hi i am having a problem with RMI.
I have this error when i run it.
java.lang.ClassCastException: com.sun.proxy.$Proxy0 cannot be cast to rmi.converter
This is the interface
converter.java
import java.rmi.RemoteException;
public interface converter {
double CelciusKelvin (double a) throws RemoteException;
double CelciusFahrenheit (double a) throws RemoteException;
double FahrenheitKelvin (double a) throws RemoteException;
double FahrenheitCelcius (double a) throws RemoteException;
double KelvinCelcius (double a) throws RemoteException;
double KelvinFahrenheit (double a) throws RemoteException;
double AtmosPascal (double a) throws RemoteException;
double AtmosPSI (double a) throws RemoteException;
double PascalAtmos (double a) throws RemoteException;
double PascalPSI (double a) throws RemoteException;
double PSIAtmos (double a) throws RemoteException;
double PSIPascal (double a) throws RemoteException;
}
This is the remote method
converterImp.java
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
public class converterImp extends UnicastRemoteObject implements converter {
public converterImp() throws RemoteException
{
}
double convert;
#Override

#Override

return convert;
}
#Override
public double FahrenheitCelcius(double a) throws RemoteException {

return convert;
}
#Override
public double KelvinCelcius(double a) throws RemoteException {
convert = a - 273.15;
return convert;
}
#Override
public double KelvinFahrenheit(double a) throws RemoteException {

return convert;

return convert;

#Override

return convert;
}
#Override
public double PascalPSI(double a) throws RemoteException {

I developed the GUI using GUI Builder on netbeans.
The problem is when i pressed jButton12. it will show the error as stated.

You appear to have created a copy of your remote interface in a different package for the client. You can't do that. The remote interface has to be the same on both sides: The Same, and that does not include changing its package, or indeed any anything else.

The game works just fine, but i am not sure how to get the winner.
I am not sure where exactly in the code i need to place it.
First i tried
if((jButton1.getText())==(jButton2.getText())&&((jButton2.getText())==(jButton3.getText()){
ganador = true;
}
but it says it's missing the return statement. Then i changed the code in order to use .equals but it says its missing a return statement again .
if(jButton1.getText().equals(jButton2.getText()) && (jButton2.getText.equals(jButton3.getText)) && (jButton2.getText() != "") {
ganador = true;
}
Also, i place this part of the code at the end but not sure if that's the problem.

The getText() function in AbstractButton returns a String, in java you need to compare Strings using the .equals(otherString) function
Edit: in regards to your missing return statement. That also means your code there isn't complete as all those methods are void. But if you say a function is: public boolean doSomething() then you need a return statement that actually returns a boolean such as: return ganador.

To further what Simon has said, you want to be implementing this along the lines of:
jButton1.getText().equals( jButton2.getText() )

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.
