How will I be able to compare two button presses from a choice of three?

I have 3 buttons
b1
b2
b3
I want to now have these buttons be pressed in turns.
So turn one I press and turn 2 another person presses.
So after turn two, I will compare the names of the buttons.
b1.addActionListener(new ActionListener() {
public void actionPerformed( ActionEvent event ) {
b1.setEnabled(false);
if (!b1.isEnabled() && !b2.isEnabled()) {
//computeWinner(b1.getText(), b2.getText());
} else if(!b1.isEnabled() && !b3.isEnabled()) {
//computeWinner(b1.getText(), b2.getText());
}
}
});
This was what I thought would work, but there are many things wrong with this,
First, since I disable the buttons the second user always has one less option. and second the if statements do not seem to work? how should I compare the
JButton b3 = new JButton ("hello"); <- hello lable of the buttons?
EDIT:
I was able to successfully compare the two buttons. Now my only problem is that for the second player one of the buttons are disabled(how can I capture the first button press and the second without disabling them?). And that after the comparison I don't know how to reset the board to go again. (for a set number of loops.)
Thank you for the help!

The following code will print the label of the button which has been pressed. I hope, you should be able to proceed from here. Feel free to let me know if you face any further issue.
ActionListener actionListener = new ActionListener(){
public void actionPerformed(ActionEvent actionEvent) {
System.out.println(actionEvent.getActionCommand());
}
};

There are several options.
Store the buttons in a map<Integer, String>. the integer would be a count for keeping track of pushes. The string would be the actionCommand of the button pressed.
Store the button actionCommands in a list or array.
In either of the above you can provide appropriate logic to compare the buttons and then reset the arrays or map and count.
Note: The actionCommand defaults to the button label unless it explicitly set.

Java set buttons names automatically

I'm new in Java swing, and I have a problem. I made for-loop for creating buttons and now I want automatically give them names or some kind of marks for future recognition (I will need name of clicked button to make it a variable).
How can I give them names in my loop? Thank you.
Here is code of my for-loop:
for (int aa=1; aa<65; aa++)
{
JButton button = new SquareButton("");
gui.add(button);
button.addActionListener((ActionListener) button);
}

I will need name of clicked button to make it a variable).
You don't need a variable to work with the clicked button. Instead you get a reference to the button that was clicked from the ActionListener code:
public void actionPerformed(ActionEvent e)
{
JButton button = (JButton)e.getSource();
// do processing on the clicked button.
}

How to add set of integers in a JTextArea

I have added set of integers to a JTextArea for each button click.
what exactly I want is that I want to add all the integers and display in a separate JTextArea,Also I want to ask whether we can access the value of a variable within an action listener outside the action listener.
Here is the code:
private ActionListener listener = new ActionListener() {
#Override
public void actionPerformed(ActionEvent evt) {
if(evt.getActionCommand().equals(t.getText()))
{
onec=one.calone(n);
td.append(Double.toString(onec));
td.append("\n");
}
res=Integer.parseInt(td.getText());
}
};
When the user presses button 't' It will keep on adding the integer 'onec' to
textarea 'td' using append method.And I have stored the result from the action
listener into a variable 'res' of double datatype.
private ActionListener listener2 = new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand().equals(tot.getText()))
{
totd.setText(Double.toString(res));
}
}
};
When the user clicks the button 'tot',It should add all the integers in the
textarea 'td' and display it in the textarea 'totd'.
This code is not working.
Please help me this is the last part of my project.

As I don't know what is not working - it would of been good if you explained more clearly - my guess is...
Instead of Double.toString(onec)
Use String.valueOf(onec)
EDIT: If this is not the case, please elaborate on what your problem is, and a fuller code listing.

converting the contents of the textArea to double does not calculate sum. Try looping throught the first textArea reading each value while calculating the sum

UI Java: Button which clears the data of a JTable

I am quite new to the creation of user interface in Java. I have been using the WindowBuilder to create an interface. I have some data from a table and I would like
The user to check if they are double or not and hit the right button (Double, not double)
Then, the variable double or the notdouble I would like to increase
And in the end, to have the table cleared from the data and display the next data from the table.
In the end, I would like to give the results of the variables (double, notdouble)
I have written a code for action listeners of the buttons, so far in
order to diplay some messages
// DOUBLE BUTTON
JButton btnDouble = new JButton("DOUBLE");
btnDouble.setFont(new Font("Calibri", Font.PLAIN, 12));
btnDouble.addActionListener(new ActionListener() { // For event handling
public void actionPerformed(ActionEvent e)
{
//Execute when button is pressed
System.out.println("You clicked the DOUBLE button");}
});
I am just writing here in order to give me some guidelines or where I should look for. Any tutorial available would be very helpful.

How to use Button and
How to use Table

Set keyboard shortcut for a JButton?

I have a type game in which you have to type the words that appear as fast as possible before the time limit runs out, but every time you type a word, you must move the mouse and click enter and click back into the user input to type the next word. I was just hoping if there was way to use "keyCode.VK_Enter" to issue an Action Command called by the JButton.
Some snippets of my code:
The Enter button and user input and output:
enter = new JButton("Enter");
enter.setFont(serif); //serif is specified earlier
enter.setActionCommand("Enter");
enter.addActionListener(this);
container.add(enter);
userOutput = new JTextField(50);
userOutput.setFont(serif);
container.add(userOutput);
userOutput.setEditable(false);
userInput = new JTextField(43);
userInput.setFont(serif);
container.add(userInput);
userInput.setEditable(false);
The actionPerformed method getting the enter button's action command:
if(userInput.getText().equals(userOutput.getText())){
userInput.setText("");
score += 100;

Why don't you just add an actionlistener to the JTextField (which would be triggered when the user hits enter).
userInput.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// Do something
}
});
