Try this link to Matthew Robinson's book "Swing." It has a chapter on printing (Chapter 22) that includes printing tables. That chapter is available in .html, Microsoft Word .doc, and .pdf formats.

Thanks for the help, Mike. I am new to object-oriented programming. It was a lot easier to fix my code than I thought it would be. I just removed the line in Class3 that creates a Class1 object and then referenced class2.class1. Works beautifully!

In the following code there is a JTextArea with an initial string. When the user changes the text in the JTextArea and clicks on update on the menu bar, class2.update() is called which in turn calls a class1.getText() method which should return the text in the JTextArea. The problem I am having is that the inital string is always returned. For troubleshooting I added a line in the actionPerformed() method that calls the same class1.getText() method. However, this time the current contents of the text are returned.
How do I get the class2.update() method to print the current contents of the JTextArea?
Also, where are the initial contents of the JTextArea being stored so that they keep being returned in the update() method?
The following code is a model of an application I am writing. If someone can help me understand what is happening here I will be able to apply it to my application.
<font size=2.5> import javax.swing.*; import javax.swing.event.*; import java.awt.*; import java.awt.event.*; class MainMenu extends JMenuBar { JMenuItem updateMenuItem = new JMenuItem("Update"); public MainMenu() { add(updateMenuItem); } public void addActionListener(ActionListener listener) { updateMenuItem.addActionListener(listener); } } class Class1 extends JPanel { JTextArea textArea = new JTextArea("Text Area",15,20); public Class1() { add(textArea);} public String getText() { return textArea.getText(); } } class Class2 extends JPanel { Class1 class1 = new Class1(); public void update() { System.out.println(class1.getText()+" ---in class2 update()"); } } public class Class3 extends JFrame implements ActionListener { Class1 class1 = new Class1(); Class2 class2 = new Class2(); MainMenu mainMenu = new MainMenu(); public Class() { setJMenuBar(mainMenu); mainMenu.addActionListener(this); getContentPane().add(class1); pack(); setVisible(true); addWindowListener (new WindowAdapter() {public void windowClosing(WindowEvent e) {System.exit(0);}});} public void actionPerformed(ActionEvent e) { class2.update(); System.out.println(class1.getText()+" ---in Class3 actionPerformed()"); } public static void main(String[] args) { Class3 application = new Class3(); } }
