create empty JDialog when changing the event

I am creating a small application in java that calculates bets automatically. When clicking on the results button, a JDialog is automatically created that shows on a TextArea the bet that has been created automatically and another that is also created automatically and makes the winner. In the same interface of the program there is a statistical button that when clicking, 1000 bets are generated automatically and compared with a winner also generated in a random way. I have the problem, in which I use the JDialog for both, and if I create a statistic before clicking on the results button, it shows me the 1000 results (up to that point). But if after I click on results, the same JDialog reopens with those results. And what I intend is that even if it is the same JDialog, it is cleaned for each action. attached code so far from the acctionListener

resultadosBt.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            if(resultadosBt.getText() == "Resultados"){

                resultados = new Resultados(apuestas, apuesta, "Resultados", ventana);
            }
        }
    }); 

estadisticaBt.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent e) {
            if(estadisticaBt.getText() == "Estadistica"){
                contador = 0;
                while(contador < 1000){
                    generaApuestaAutomatica();
                    contador++;
                }
                resultados = new Resultados(apuestas, apuesta, "Estadistica", ventana);
            }
        }
    });

This is the interface, so you can get an idea:

When I click on statistics, the 1000 bets are created and compared with a winner and everything is shown in a JDialog:

When I click on results it should appear empty unless I give the automatic button, which then stores the bets and shows them in results.
