Answer 1

1. First you have to add JButton to frame
2. Than add ActionListener in button

3. than make a list when button is pressed like this

   JButton b = new JButton("Click Me");
   b.addActionListener(new ActionListener() {
   
   public void actionPerformed(ActionEvent e) {
   
   String[] columnNames = {"First Name",
               "Last Name",
               "Sport",
               "# of Years",
               "Vegetarian"};
   
   Object[][] data = {
               {"Kathy", "Smith",
                "Snowboarding", new Integer(5), new Boolean(false)},
               {"John", "Doe",
                "Rowing", new Integer(3), new Boolean(true)},
               {"Sue", "Black",
                "Knitting", new Integer(2), new Boolean(false)},
               {"Jane", "White",
                "Speed reading", new Integer(20), new Boolean(true)},
               {"Joe", "Brown",
                "Pool", new Integer(10), new Boolean(false)}
           };
   
       JTable table = new JTable(data, columnNames);
       add(table);
