如何使用 Netbeans GUI 编辑器检查单击了哪个按钮

Question

Currently I am designing my GUI form and I am wondering about one thing. Here is my GUI:

I want to add the same ActionPerformed method to all of these buttons, but in ActionListener only one parameter can be set (or I dont know how to change it), that is ActionEvent evt.

My question is : how to add another parameter to be sent to ActionPerformed, according to which button was clicked, and then lets say print in console text from button?

It is not possible to do it while just editing code (ActionListener) because NetBeans editor blocks such things.

Thanks in advance.

and then lets say print in console text from button?

You write a generic listener. The ActionEvent contains the button that was clicked.

The basic logic would be:

ActionListener al = new ActionListener()
{
    @Override
    public void actionPerformed(ActionEvent e)
    {
        JButton button = (JButton)e.getSource();
        System.out.println( button.getText() );
    }
}

...

button1.addActionListener( al );
button2.addActionListener( al );
