Question

I am a beginner in Java and I need help.

I want to add table with rows and columns in JFrame or JPanel when a button is clicked. How to add new table with rows and columns by clicking button?

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); } });
