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]));

            }
        });

Take a look at this link: http://stackoverflow.com/questions/3549206/how-to-add-row-in-jtable. It seems like what you want to do. — ديناصور الأمة, Mar 23 '14 at 11:27
I dont know what raw it.. I am basically just trying to print a address on two lines the easiest way possible using a onclick function. — wuno, Mar 23 '14 at 11:27
Can you post the whole code of class where you use `Jtable`? — ديناصور الأمة, Mar 23 '14 at 11:29
I'm can't see there anything about JTable (excl. JTable tbl1 = new JTable();), read official Oracle tutorial How to use Table — mKorbel, Mar 23 '14 at 11:42
I add the Jtable then I am trying to set the text. I have read the tutorial I am not understanding what I am missing. thanks for your input though. tbl1.setText(ShippingLabel(sl)); — wuno, Mar 23 '14 at 11:43

`p.setLayout(null);` Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or [combinations of them](http://stackoverflow.com/a/5630271/418556), along with layout padding & borders for [white space](http://stackoverflow.com/q/17874717/418556). — Andrew Thompson, Mar 23 '14 at 11:54
I think your saying that the way im making this is wrong. this is for school and the things im am illustrating are just fine the way they are. the last thing I need to work is to print the address when I click a button. all i need to know how to do is make the button work. — wuno, Mar 23 '14 at 11:56

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]));

    }
});
