How to generate multiple buttons with the same variable and catch them separately

Question

Hello, I’ll put the important part of the code here and then I’ll explain what I want to do.

Main:

public static JButton sala;
public static int contagemTurmas = 0;

botaoSalvar.addActionListener(new ActionListener() 
    {
        public void actionPerformed(ActionEvent e) 
        {   
            gerarTableTurma(turmaName.getText(), contagemTurmas, panelCriados);
        }
    });

sala.addActionListener(new ActionListener() 
    {
        public void actionPerformed(ActionEvent e) 
        {
            System.out.println(sala.getText());
            turmaName.setText(sala.getText());
        }
    });

Part generating the various buttons from the vairavel sala

public static void gerarTableTurma(String turma, int posicao, JPanel panel) 
{   
    sala = new JButton(turma); //turma = JTextArea
    sala.setFont(new Font("Tahoma", Font.PLAIN, 30));
    sala.setBounds(10, 11 + (contagemTurmas * 43), 792, 32);
    panel.add(sala);

    contagemTurmas ++;

    panel.repaint();
}

I would like to take the event from a button, however do not know the button, so I created several buttons in the same variable, so no matter what button clicked, I would know which would be just testing the variable sala, how can I do that ?? since when I click on one of the buttons nothing happens at all
