How do I add the resulting arrayList from each button press as a separate element in another arrrayList

Each time the button is pressed, the result is saved as an arrayList to another arrayList. Problem is it's appending it to the previous element. I need to be able to add the results of each press as a separate element. For example: first press: [5, 3, 5, 2, 6, 5] second press would display: [5, 3, 5, 2, 6, 5][2, 1, 4, 1, 4, 1] This way I can loop through and get each array result separately. How do I do this?

public class mainClass{
        public static void main(String[] args){
JFrame frame1 = new JFrame("testButton");
frame1.setDefaultCloseOperation(JFrame. EXIT_ON_CLOSE);
buttonExample b1 = new buttonExample();
frame1.getContentPane().add(b1);
frame1.pack();
frame1.setVisible(true);
            }

    }

    public class Example {
            private int rand1;
            private ArrayList<ArrayList> count;
            private ArrayList<Integer> count2;
            private Random rnd;
            private int counter1;
            private ArrayList<ArrayList>count3;
        public Example(){
            count = new ArrayList<ArrayList>();
            count2 = new ArrayList<Integer>();
            rnd = new Random();
            count3 = new ArrayList<ArrayList>();
}
        private void addCount2(){
            for(int x = 0; x<6;x++){
            rand1 = rnd.nextInt(6)+1;
            count2.add(rand1);// count2 == Integers
            }
        }

        public void addCount(){
            addCount2();
            count.add(count2);// count == count3
        }
        public ArrayList<ArrayList> displayCount(){
        return count;

        }
}

public class buttonExample extends JPanel {
private JButton button1;
private Example example1;
public buttonExample(){
button1 = new JButton("Submit");
add(button1);
button1.addActionListener(new ButtonListener());
example1 = new Example();
}
private class ButtonListener implements ActionListener{
public void actionPerformed(ActionEvent e) {
    example1.addCount();
    System.out.println(example1.displayCount().get(0));;
    }
}
}
