I've been trying to follow the information here and and the code here and I'm having some difficulty.
The database query works and I've outputted it successfully to console. Following the above guides I've since added some code that puts the ResultSet data into the required Vectors. This is my code:

The final part of the code, which I believe out puts to the table, gives me some weird errors.
// Out put to the table (theoretically)
JTable table = new JTable(columnNames, data);
this.scrollPane.setViewportView(table);
// JScrollPane scrollPane = new JScrollPane( table );
// getContentPane().add( scrollPane );
The first line gives me a syntax error on the semi-colon (;), specifically, Syntax error on token ";", invalid AssignmentOperator. I get the same when I try the 'model' variable.
When I uncomment the last two lines I get 'Syntax error on token ".", { expected' and the Eclipse demands another closing { despite there not being a corresponding opening }. If I add it then I get more errors.
I suspect this has something to do with the class structure of the code that I'm trying to follow but I'm having no luck in following those either.
All I want to do is to take the information that I have and output it in the table which is already there. How do I do this?
You're not showing all the error messages nor the complete error messages (please fix this). The most important one is the, Cannot refer to the non-final local variable data defined in an enclosing scope message. So make the variables final -- one problem solved.
public void Bookings() {
// Local variables
final Vector<Object> columnNames = new Vector<Object>(); //!! made final
final Vector<Object> data = new Vector<Object>();
The other problem is that this code:
JTable table = new JTable(columnNames, data);
this.scrollPane.setViewportView(table);
Is being called outside of any and all methods. You need to match up your curly braces carefully.
Question that confuses me about your code though -- why create a TableModel and not use it as a model for your JTable?
scrollPane is not a global instance.
Move JScrollPane scrollPane out of your method SearchFrame() and place it into your list of instance variables for the class.
That is only your immediate and first issue, your other issue is that your are attempting to access instance variables defined in Reports within the scope of 2x nested anonymous classes.
You should parametarize your GUI methods to accept the components for injection into the panels.
public class Reports extends JFrame {
JScrollPane scrollPane;
...
private void SearchFrame() {
scrollPane = new JScrollPane ();
}
...
public void Bookings() {
scrollPane...
...
}
...
}

So in my code, I have 2 JTextField inputs that need input for the rest of the program to work. Both of them contain variables that cannot be left empty for the rest of the program to work. The problem is that whenever you enter something into the text field, you have to press enter in the end and that process is not that straightforward in the program as you are not able to see whether or not you have already pressed enter without looking into the console.
ActionListener buttonlistener2 = new ActionListener() {

please help getting "java:23 error: '{' expected" to me the brackets look right, appreciate the help!
is there something else that I am missing? I've only just started getting into writing code and so far have loved it. I've done c# and visual basics as well as now taking Java.

The } after private EventHandler eHandler; will close the class definition, which is not what you are wanting.
Also public class PizzaShop() { would be wrong and not needed. Maybe you are thinking of a constructor?
I suggest that you use a IDE like eclipse which allows you to click on menu items to create classes etc.
Your closing brace on line 22 is finishing the class definition and the code after that seems to be trying to re-start it. Get rid of it. You should have:
private JLabel orderL;
private EventHandler eHandler;
public void init() { ...
There is an extra closing brace before
public class PizzaShop()
And I presume the above line is meant to be a constructor, not another class declaration:
public PizzaShop() {
}
You can't have the same class defined twice in a file, in fact each class should probably be in another file (or it needs to be an inner class of some kind) -
public class PizzaShop extends JApplet
{
//Declare variables
private int intBold;
private JCheckbox tomatoCB, grennPepperCB, blackOliveCB;
private JCheckBox MushroomCB, extraCheeseCB, pepperoniCB, sausageCB;

private ButtonGroup sizeBG, typeBG;
private JTextArea textArea;
private Jbutton processB;
private JLabel orderL;
private EventHandler eHandler;
} // <-- Here
public class PizzaShop() // <-- we just did this class.
I'm still a little new to Java and a complete noob to Gui's. I can't for the life of me figure out how to add the data from my String array into the Jtable. I tried to read the docs on oracle but it was not making sense to me for my particular situation. If you guys could please point me in the right direction I would appreciate it. Also I'm retrieving my array data from a file. Not sure if that makes a difference.

Follow this tutorial:
http://docs.oracle.com/javase/tutorial/uiswing/components/table.html
The main idea is, that swing is built on the principles of MVC architecture. What that means for you is that the component that is responsible for displaying the table (JTable), and the component that knows what is in the table (TableModel) are separated. You somehow need to pass the model to the table. You can either use the DefaultTableModel, which is what you did, or define your own model that implements the interface TableModel.
For the first, you need to pass in an array to the constructor of DefaultTableModel.
For the latter you need to implement methods that - among others - query data at certain positions, but this is worth considering only if the out of the box stuff does not do it for you.
On a side note about error messages: if you are serious about programming, don't get used to bad patterns. They might seem easier now, but they are ill-advised for a reason. They usually don't scale well from a hello-world size project to a full blown project developed by multiple people. Stacktrace is your friend. Use a logger instead of sysout. It will be easier for you in the long run if you get used to good practices now.
I was trying to build the Font window of Notepad using Java using the code shown below. But, I'm facing a problem in setting the size of the text as specified inside listbox.
I'm trying to get the respective size corresponding to the index of the selected item but couldn't find any such method.
f = new Frame("Font");
f.setLayout(new GridLayout(3, 3));
b1 = new Button("OK");
l1 = new Label("Font :");
l2 = new Label("Size :");
l3 = new Label("Font Style :");
lb1 = new List(10, false);
lb2 = new List(10, false);
lb3 = new List(5, false);
String [] s = {"Times New Roman", "Arial", "Verdana", "Trebuchet MS", "Papyrus","Monotype Corsiva","Microsoft Sans Serif", "Courier", "Courier New"};
for(int i = 0; i < s.length; i++)
{
lb1.add(s[i]);
}
for(int i = 8; i <=72; i += 2)
{
lb2.add(i + "");
}
String [] s1 = {"BOLD", "ITALIC", "PLAIN"};
for(int i = 0; i < s1.length; i++)
{
lb3.add(s1[i]);
}
f.add(l1);
f.add(l2);
f.add(l3);
f.add(lb1);
f.add(lb2);
f.add(lb3);
f.add(b1);
b1.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent ae)
{
if(lb3.isIndexSelected(0))
fo = new Font(lb1.getSelectedItem(), Font.BOLD, **lb2.getSelectedIndex**());
else if(lb3.isIndexSelected(1))
fo = new Font(lb1.getSelectedItem(), Font.ITALIC, lb2.getSelectedIndex());
else
fo = new Font(lb1.getSelectedItem(), Font.PLAIN, lb2.getSelectedIndex());
ta1.setFont(fo);
MyFrame15.f.dispose();
}
});
f.setSize(300, 300);
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
int x = (int)((d.getWidth() / 2) - 200);
int y = (int)((d.getHeight() / 2) - 200);
f.setLocation(x, y);
f.setVisible(true);
}
To get the size as required by user we can use:
lb2.getSelectedItem();
which returns a String but the third argument of Font constructor requires an integer.Therefore, we use parseInt() method of Integer class to convert the string received to integer.The code is as follows:
Font(lb1.getSelectedItem(), Font.BOLD, Integer.parseInt(lb2.getSelectedItem()));
I would suggest you use Swing for this. You can start with the Swing tutorial on Text Component Features which already contains a working example that does what you want.

int month = 0;
if (date > 500) {
sex = "Feamale";
date -= 500;
} else {
sex = "Male";
}
int datesOfMonths[] = { 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31 };
for (int i = 0; i < 12; i++) {

}
I just created a program for find birthday from nic. I couldn't fix this compile error.
I created a JTextField to get Nic, then I added substring methods to get the needed numbers to find nic. Unfortunately the substring methods can't find textField. It shows error as 'cannot find symbol'. It's a TextField. Why can't the method find that TextField.?
The message:
cannot find symbol
Is not referring to the text field, but the method substring(..) which does not exist for JTextField. But something like..
textField.getText().substring(...);
..probably will work, since getText() returns a String and String has that method.
Change
String yearText = nicText.substring(0, 2);
String dateText = nicText.substring(2, 5);
to
String yearText = nicText.getText().substring(0, 2);
String dateText = nicText.getText().substring(2, 5);
