title: How to retrieve information from one class to another
body: <p>I have the following code to retrieve information from a text box to another within the same class</p>
  
  <pre><code>btnAddItem.addActionListener(new ActionListener() {
       public void actionPerformed(ActionEvent e) {
  
           String tabno = textArea_TableNo.getText();
           String name = textArea_Name.getText();
           String size = textArea_size.getText();
           String quan = textArea_quantity.getText();
           String price = textArea_price.getText();
           textArea.append(tabno + ",    " + name + ",    " + size + ",    " + quan + ",    " + price + "\n");
  </code></pre>
  
  <p>But I am not sure how to do this exactly same operation between two class. I probably have to "extend" my class but I've already extended the class to my database class. Im just not sure how else I can do this. Any suggestions to get my head around this would be appreciated..</p>
