array in the address class

    public void ShippingLabel(String[]args) {
  Object [][] sl = {{"555 Hello Ln", "Capital, TX 77777"}};
    }

in the main class

  btn1.addMouseListener(new java.awt.event.MouseAdapter() {
            public void mouseClicked(java.awt.event.MouseEvent evt) {
                btn1MouseClicked(evt);
                tbl1.setText(ShippingLabel(sl[0]));

            }
        });

Answer 1

Use DefaultTableModel to add a new row in JTable

Sample code:

• Here table having 4 existing rows

• A new row is added on button click

   Object data[][] = { { "111Hello Ln", "Capital", "TX 77777" }, { "222 Hello Ln", "Capital", "TX 77777" }, { "333 Hello Ln", "Capital", "TX 77777" }, { "444 Hello Ln", "Capital", "TX 77777" } }; String col[] = { "Name", "Capital", "TX" }; final DefaultTableModel model = new DefaultTableModel(data, col); final JTable table = new JTable(model); .... btn1.addMouseListener(new java.awt.event.MouseAdapter() { public void mouseClicked(java.awt.event.MouseEvent evt) { btn1MouseClicked(evt); Object [][] sl = {{"555 Hello Ln", "Capital", "TX 77777"}}; model.addRow(ShippingLabel(sl[0])); } });
